Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18084, here are decompositions:

  • 7 + 18077 = 18084
  • 23 + 18061 = 18084
  • 37 + 18047 = 18084
  • 41 + 18043 = 18084
  • 43 + 18041 = 18084
  • 71 + 18013 = 18084
  • 97 + 17987 = 18084
  • 103 + 17981 = 18084

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18084 first appears in π at position 84,338 of the decimal expansion (the 84,338ordinal-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.
