Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521798, here are decompositions:

  • 7 + 521791 = 521798
  • 31 + 521767 = 521798
  • 127 + 521671 = 521798
  • 139 + 521659 = 521798
  • 157 + 521641 = 521798
  • 241 + 521557 = 521798
  • 271 + 521527 = 521798
  • 307 + 521491 = 521798

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 521,798 and was likely granted around 1894.

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

Position in π

The digit sequence 521798 first appears in π at position 873,665 of the decimal expansion (the 873,665ordinal-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.
