Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520438, here are decompositions:

  • 5 + 520433 = 520438
  • 11 + 520427 = 520438
  • 29 + 520409 = 520438
  • 59 + 520379 = 520438
  • 89 + 520349 = 520438
  • 131 + 520307 = 520438
  • 197 + 520241 = 520438
  • 419 + 520019 = 520438

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 520,438 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 520438 first appears in π at position 57,748 of the decimal expansion (the 57,748ordinal-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.
