Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520436, here are decompositions:

  • 3 + 520433 = 520436
  • 13 + 520423 = 520436
  • 43 + 520393 = 520436
  • 67 + 520369 = 520436
  • 73 + 520363 = 520436
  • 79 + 520357 = 520436
  • 97 + 520339 = 520436
  • 127 + 520309 = 520436

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 520,436 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 520436 first appears in π at position 571,908 of the decimal expansion (the 571,908ordinal-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.
