Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553642, here are decompositions:

  • 41 + 553601 = 553642
  • 53 + 553589 = 553642
  • 59 + 553583 = 553642
  • 113 + 553529 = 553642
  • 179 + 553463 = 553642
  • 389 + 553253 = 553642
  • 431 + 553211 = 553642
  • 449 + 553193 = 553642

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 553,642 and was likely granted around 1895.

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

Position in π

The digit sequence 553642 first appears in π at position 349,247 of the decimal expansion (the 349,247ordinal-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.
