Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993872, here are decompositions:

  • 3 + 993869 = 993872
  • 31 + 993841 = 993872
  • 79 + 993793 = 993872
  • 109 + 993763 = 993872
  • 193 + 993679 = 993872
  • 283 + 993589 = 993872
  • 331 + 993541 = 993872
  • 379 + 993493 = 993872

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 993,872 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 993872 first appears in π at position 407,586 of the decimal expansion (the 407,586ordinal-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.
