Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2242, here are decompositions:

  • 3 + 2239 = 2242
  • 5 + 2237 = 2242
  • 29 + 2213 = 2242
  • 89 + 2153 = 2242
  • 101 + 2141 = 2242
  • 113 + 2129 = 2242
  • 131 + 2111 = 2242
  • 173 + 2069 = 2242

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2242 first appears in π at position 5,838 of the decimal expansion (the 5,838ordinal-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.
