Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511620, here are decompositions:

  • 17 + 511603 = 511620
  • 29 + 511591 = 511620
  • 37 + 511583 = 511620
  • 41 + 511579 = 511620
  • 47 + 511573 = 511620
  • 61 + 511559 = 511620
  • 71 + 511549 = 511620
  • 79 + 511541 = 511620

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 511,620 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 511620 first appears in π at position 14,548 of the decimal expansion (the 14,548ordinal-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.
