Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521012, here are decompositions:

  • 3 + 521009 = 521012
  • 31 + 520981 = 521012
  • 43 + 520969 = 521012
  • 199 + 520813 = 521012
  • 313 + 520699 = 521012
  • 379 + 520633 = 521012
  • 463 + 520549 = 521012
  • 601 + 520411 = 521012

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 521,012 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 521012 first appears in π at position 626,394 of the decimal expansion (the 626,394ordinal-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.
