Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505458, here are decompositions:

  • 11 + 505447 = 505458
  • 29 + 505429 = 505458
  • 47 + 505411 = 505458
  • 59 + 505399 = 505458
  • 89 + 505369 = 505458
  • 101 + 505357 = 505458
  • 131 + 505327 = 505458
  • 137 + 505321 = 505458

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 505,458 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 505458 first appears in π at position 683,937 of the decimal expansion (the 683,937ordinal-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.
