Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498688, here are decompositions:

  • 41 + 498647 = 498688
  • 89 + 498599 = 498688
  • 131 + 498557 = 498688
  • 137 + 498551 = 498688
  • 167 + 498521 = 498688
  • 191 + 498497 = 498688
  • 227 + 498461 = 498688
  • 431 + 498257 = 498688

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 498,688 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 498688 first appears in π at position 139,761 of the decimal expansion (the 139,761ordinal-suffix:st 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.
