Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487938, here are decompositions:

  • 5 + 487933 = 487938
  • 41 + 487897 = 487938
  • 47 + 487891 = 487938
  • 107 + 487831 = 487938
  • 109 + 487829 = 487938
  • 127 + 487811 = 487938
  • 149 + 487789 = 487938
  • 181 + 487757 = 487938

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 487,938 and was likely granted around 1892.

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

Position in π

The digit sequence 487938 first appears in π at position 114,653 of the decimal expansion (the 114,653ordinal-suffix:rd 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.
