Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574336, here are decompositions:

  • 7 + 31574329 = 31574336
  • 103 + 31574233 = 31574336
  • 163 + 31574173 = 31574336
  • 229 + 31574107 = 31574336
  • 337 + 31573999 = 31574336
  • 379 + 31573957 = 31574336
  • 709 + 31573627 = 31574336
  • 823 + 31573513 = 31574336

Showing the first eight; more decompositions exist.
