Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561072, here are decompositions:

  • 11 + 561061 = 561072
  • 13 + 561059 = 561072
  • 19 + 561053 = 561072
  • 53 + 561019 = 561072
  • 103 + 560969 = 561072
  • 131 + 560941 = 561072
  • 179 + 560893 = 561072
  • 181 + 560891 = 561072

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 561,072 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 561072 first appears in π at position 704,605 of the decimal expansion (the 704,605ordinal-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.
