Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18608, here are decompositions:

  • 67 + 18541 = 18608
  • 127 + 18481 = 18608
  • 151 + 18457 = 18608
  • 157 + 18451 = 18608
  • 181 + 18427 = 18608
  • 211 + 18397 = 18608
  • 229 + 18379 = 18608
  • 241 + 18367 = 18608

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18608 first appears in π at position 4,783 of the decimal expansion (the 4,783ordinal-suffix:rd 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.
