Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521102, here are decompositions:

  • 61 + 521041 = 521102
  • 79 + 521023 = 521102
  • 139 + 520963 = 521102
  • 181 + 520921 = 521102
  • 691 + 520411 = 521102
  • 709 + 520393 = 521102
  • 733 + 520369 = 521102
  • 739 + 520363 = 521102

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 521,102 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 521102 first appears in π at position 566,978 of the decimal expansion (the 566,978ordinal-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.
