Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572420, here are decompositions:

  • 3 + 572417 = 572420
  • 97 + 572323 = 572420
  • 109 + 572311 = 572420
  • 139 + 572281 = 572420
  • 151 + 572269 = 572420
  • 181 + 572239 = 572420
  • 241 + 572179 = 572420
  • 283 + 572137 = 572420

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 572,420 and was likely granted around 1896.

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

Position in π

The digit sequence 572420 first appears in π at position 212,048 of the decimal expansion (the 212,048ordinal-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.
