Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517442, here are decompositions:

  • 31 + 517411 = 517442
  • 43 + 517399 = 517442
  • 61 + 517381 = 517442
  • 139 + 517303 = 517442
  • 181 + 517261 = 517442
  • 193 + 517249 = 517442
  • 199 + 517243 = 517442
  • 313 + 517129 = 517442

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 517,442 and was likely granted around 1894.

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

Position in π

The digit sequence 517442 first appears in π at position 909,247 of the decimal expansion (the 909,247ordinal-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.
