Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18098, here are decompositions:

  • 37 + 18061 = 18098
  • 109 + 17989 = 18098
  • 127 + 17971 = 18098
  • 139 + 17959 = 18098
  • 271 + 17827 = 18098
  • 307 + 17791 = 18098
  • 337 + 17761 = 18098
  • 349 + 17749 = 18098

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18098 first appears in π at position 177,615 of the decimal expansion (the 177,615ordinal-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.
