Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493388, here are decompositions:

  • 19 + 493369 = 493388
  • 37 + 493351 = 493388
  • 97 + 493291 = 493388
  • 109 + 493279 = 493388
  • 139 + 493249 = 493388
  • 157 + 493231 = 493388
  • 211 + 493177 = 493388
  • 229 + 493159 = 493388

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 493,388 and was likely granted around 1893.

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

Position in π

The digit sequence 493388 first appears in π at position 90,906 of the decimal expansion (the 90,906ordinal-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.
