Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18674, here are decompositions:

  • 3 + 18671 = 18674
  • 13 + 18661 = 18674
  • 37 + 18637 = 18674
  • 151 + 18523 = 18674
  • 157 + 18517 = 18674
  • 181 + 18493 = 18674
  • 193 + 18481 = 18674
  • 223 + 18451 = 18674

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18674 first appears in π at position 209,763 of the decimal expansion (the 209,763ordinal-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.
