Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11018, here are decompositions:

  • 31 + 10987 = 11018
  • 61 + 10957 = 11018
  • 79 + 10939 = 11018
  • 109 + 10909 = 11018
  • 127 + 10891 = 11018
  • 151 + 10867 = 11018
  • 157 + 10861 = 11018
  • 181 + 10837 = 11018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11018 first appears in π at position 93,256 of the decimal expansion (the 93,256ordinal-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.
