Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511480, here are decompositions:

  • 3 + 511477 = 511480
  • 17 + 511463 = 511480
  • 23 + 511457 = 511480
  • 41 + 511439 = 511480
  • 71 + 511409 = 511480
  • 89 + 511391 = 511480
  • 191 + 511289 = 511480
  • 257 + 511223 = 511480

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 511,480 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 511480 first appears in π at position 624,007 of the decimal expansion (the 624,007ordinal-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.
