Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18466, here are decompositions:

  • 5 + 18461 = 18466
  • 23 + 18443 = 18466
  • 53 + 18413 = 18466
  • 113 + 18353 = 18466
  • 137 + 18329 = 18466
  • 179 + 18287 = 18466
  • 197 + 18269 = 18466
  • 233 + 18233 = 18466

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18466 first appears in π at position 174,041 of the decimal expansion (the 174,041ordinal-suffix:st 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.
