Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90100, here are decompositions:

  • 11 + 90089 = 90100
  • 29 + 90071 = 90100
  • 41 + 90059 = 90100
  • 47 + 90053 = 90100
  • 83 + 90017 = 90100
  • 89 + 90011 = 90100
  • 137 + 89963 = 90100
  • 191 + 89909 = 90100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 90100 first appears in π at position 205,106 of the decimal expansion (the 205,106ordinal-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.
