Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509578, here are decompositions:

  • 5 + 509573 = 509578
  • 29 + 509549 = 509578
  • 101 + 509477 = 509578
  • 137 + 509441 = 509578
  • 149 + 509429 = 509578
  • 281 + 509297 = 509578
  • 431 + 509147 = 509578
  • 491 + 509087 = 509578

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 509,578 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 509578 first appears in π at position 597,554 of the decimal expansion (the 597,554ordinal-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.
