Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511682, here are decompositions:

  • 13 + 511669 = 511682
  • 79 + 511603 = 511682
  • 103 + 511579 = 511682
  • 109 + 511573 = 511682
  • 163 + 511519 = 511682
  • 229 + 511453 = 511682
  • 331 + 511351 = 511682
  • 349 + 511333 = 511682

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 511,682 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 511682 first appears in π at position 281,925 of the decimal expansion (the 281,925ordinal-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.
