Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27018, here are decompositions:

  • 7 + 27011 = 27018
  • 31 + 26987 = 27018
  • 37 + 26981 = 27018
  • 59 + 26959 = 27018
  • 67 + 26951 = 27018
  • 71 + 26947 = 27018
  • 97 + 26921 = 27018
  • 127 + 26891 = 27018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27018 first appears in π at position 189,221 of the decimal expansion (the 189,221ordinal-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.
