Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42370, here are decompositions:

  • 11 + 42359 = 42370
  • 47 + 42323 = 42370
  • 71 + 42299 = 42370
  • 89 + 42281 = 42370
  • 113 + 42257 = 42370
  • 131 + 42239 = 42370
  • 149 + 42221 = 42370
  • 173 + 42197 = 42370

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42370 first appears in π at position 80,816 of the decimal expansion (the 80,816ordinal-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.
