Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157706, here are decompositions:

  • 37 + 157669 = 157706
  • 67 + 157639 = 157706
  • 79 + 157627 = 157706
  • 127 + 157579 = 157706
  • 163 + 157543 = 157706
  • 193 + 157513 = 157706
  • 223 + 157483 = 157706
  • 229 + 157477 = 157706

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 157,706 and was likely granted around 1873.

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

Position in π

The digit sequence 157706 first appears in π at position 413,819 of the decimal expansion (the 413,819ordinal-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.
