Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18046, here are decompositions:

  • 3 + 18043 = 18046
  • 5 + 18041 = 18046
  • 59 + 17987 = 18046
  • 89 + 17957 = 18046
  • 107 + 17939 = 18046
  • 137 + 17909 = 18046
  • 239 + 17807 = 18046
  • 257 + 17789 = 18046

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18046 first appears in π at position 24,700 of the decimal expansion (the 24,700ordinal-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.
