Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538590, here are decompositions:

  • 11 + 538579 = 538590
  • 23 + 538567 = 538590
  • 29 + 538561 = 538590
  • 37 + 538553 = 538590
  • 61 + 538529 = 538590
  • 67 + 538523 = 538590
  • 71 + 538519 = 538590
  • 79 + 538511 = 538590

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 538,590 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 538590 first appears in π at position 987,650 of the decimal expansion (the 987,650ordinal-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.
