Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27154, here are decompositions:

  • 11 + 27143 = 27154
  • 47 + 27107 = 27154
  • 137 + 27017 = 27154
  • 167 + 26987 = 27154
  • 173 + 26981 = 27154
  • 227 + 26927 = 27154
  • 233 + 26921 = 27154
  • 251 + 26903 = 27154

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27154 first appears in π at position 52,850 of the decimal expansion (the 52,850ordinal-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.
