Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578438, here are decompositions:

  • 19 + 578419 = 578438
  • 31 + 578407 = 578438
  • 37 + 578401 = 578438
  • 67 + 578371 = 578438
  • 127 + 578311 = 578438
  • 139 + 578299 = 578438
  • 229 + 578209 = 578438
  • 271 + 578167 = 578438

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 578,438 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 578438 first appears in π at position 1,794 of the decimal expansion (the 1,794ordinal-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.
