Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580336, here are decompositions:

  • 13 + 31580323 = 31580336
  • 19 + 31580317 = 31580336
  • 43 + 31580293 = 31580336
  • 79 + 31580257 = 31580336
  • 97 + 31580239 = 31580336
  • 103 + 31580233 = 31580336
  • 223 + 31580113 = 31580336
  • 283 + 31580053 = 31580336

Showing the first eight; more decompositions exist.
