Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18496, here are decompositions:

  • 3 + 18493 = 18496
  • 53 + 18443 = 18496
  • 83 + 18413 = 18496
  • 167 + 18329 = 18496
  • 227 + 18269 = 18496
  • 239 + 18257 = 18496
  • 263 + 18233 = 18496
  • 347 + 18149 = 18496

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18496 first appears in π at position 129,402 of the decimal expansion (the 129,402ordinal-suffix:nd 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.
