Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538658, here are decompositions:

  • 7 + 538651 = 538658
  • 37 + 538621 = 538658
  • 61 + 538597 = 538658
  • 79 + 538579 = 538658
  • 97 + 538561 = 538658
  • 139 + 538519 = 538658
  • 349 + 538309 = 538658
  • 409 + 538249 = 538658

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 538,658 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 538658 first appears in π at position 709,280 of the decimal expansion (the 709,280ordinal-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.
