Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521496, here are decompositions:

  • 5 + 521491 = 521496
  • 13 + 521483 = 521496
  • 67 + 521429 = 521496
  • 97 + 521399 = 521496
  • 103 + 521393 = 521496
  • 127 + 521369 = 521496
  • 137 + 521359 = 521496
  • 139 + 521357 = 521496

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 521,496 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 521496 first appears in π at position 784,101 of the decimal expansion (the 784,101ordinal-suffix:st 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.
