Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491296, here are decompositions:

  • 7 + 31491289 = 31491296
  • 13 + 31491283 = 31491296
  • 43 + 31491253 = 31491296
  • 97 + 31491199 = 31491296
  • 103 + 31491193 = 31491296
  • 307 + 31490989 = 31491296
  • 313 + 31490983 = 31491296
  • 379 + 31490917 = 31491296

Showing the first eight; more decompositions exist.
