Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509788, here are decompositions:

  • 5 + 509783 = 509788
  • 47 + 509741 = 509788
  • 89 + 509699 = 509788
  • 101 + 509687 = 509788
  • 107 + 509681 = 509788
  • 197 + 509591 = 509788
  • 239 + 509549 = 509788
  • 311 + 509477 = 509788

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 509,788 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 509788 first appears in π at position 972,147 of the decimal expansion (the 972,147ordinal-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.
