Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509020, here are decompositions:

  • 47 + 508973 = 509020
  • 59 + 508961 = 509020
  • 89 + 508931 = 509020
  • 101 + 508919 = 509020
  • 107 + 508913 = 509020
  • 173 + 508847 = 509020
  • 179 + 508841 = 509020
  • 293 + 508727 = 509020

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 509,020 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 509020 first appears in π at position 988,401 of the decimal expansion (the 988,401ordinal-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.
