Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625412, here are decompositions:

  • 11 + 31625401 = 31625412
  • 19 + 31625393 = 31625412
  • 29 + 31625383 = 31625412
  • 31 + 31625381 = 31625412
  • 61 + 31625351 = 31625412
  • 109 + 31625303 = 31625412
  • 131 + 31625281 = 31625412
  • 149 + 31625263 = 31625412

Showing the first eight; more decompositions exist.
