Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541642, here are decompositions:

  • 11 + 541631 = 541642
  • 29 + 541613 = 541642
  • 53 + 541589 = 541642
  • 71 + 541571 = 541642
  • 113 + 541529 = 541642
  • 131 + 541511 = 541642
  • 173 + 541469 = 541642
  • 251 + 541391 = 541642

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 541,642 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 541642 first appears in π at position 473,369 of the decimal expansion (the 473,369ordinal-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.
