Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558242, here are decompositions:

  • 19 + 558223 = 558242
  • 103 + 558139 = 558242
  • 151 + 558091 = 558242
  • 379 + 557863 = 558242
  • 439 + 557803 = 558242
  • 463 + 557779 = 558242
  • 499 + 557743 = 558242
  • 571 + 557671 = 558242

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 558,242 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 558242 first appears in π at position 370,546 of the decimal expansion (the 370,546ordinal-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.
