Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993680, here are decompositions:

  • 139 + 993541 = 993680
  • 199 + 993481 = 993680
  • 229 + 993451 = 993680
  • 283 + 993397 = 993680
  • 313 + 993367 = 993680
  • 397 + 993283 = 993680
  • 433 + 993247 = 993680
  • 439 + 993241 = 993680

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 993,680 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 993680 first appears in π at position 69,750 of the decimal expansion (the 69,750ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
