Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538320, here are decompositions:

  • 11 + 538309 = 538320
  • 17 + 538303 = 538320
  • 19 + 538301 = 538320
  • 23 + 538297 = 538320
  • 37 + 538283 = 538320
  • 53 + 538267 = 538320
  • 61 + 538259 = 538320
  • 71 + 538249 = 538320

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 538,320 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 538320 first appears in π at position 765,547 of the decimal expansion (the 765,547ordinal-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.
