Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2236, here are decompositions:

  • 23 + 2213 = 2236
  • 29 + 2207 = 2236
  • 83 + 2153 = 2236
  • 107 + 2129 = 2236
  • 137 + 2099 = 2236
  • 149 + 2087 = 2236
  • 167 + 2069 = 2236
  • 173 + 2063 = 2236

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2236 first appears in π at position 5,142 of the decimal expansion (the 5,142ordinal-suffix:nd 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.
