Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18174, here are decompositions:

  • 5 + 18169 = 18174
  • 31 + 18143 = 18174
  • 41 + 18133 = 18174
  • 43 + 18131 = 18174
  • 47 + 18127 = 18174
  • 53 + 18121 = 18174
  • 97 + 18077 = 18174
  • 113 + 18061 = 18174

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18174 first appears in π at position 163,316 of the decimal expansion (the 163,316ordinal-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.
