Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537350, here are decompositions:

  • 11 + 31537339 = 31537350
  • 23 + 31537327 = 31537350
  • 37 + 31537313 = 31537350
  • 41 + 31537309 = 31537350
  • 43 + 31537307 = 31537350
  • 79 + 31537271 = 31537350
  • 83 + 31537267 = 31537350
  • 107 + 31537243 = 31537350

Showing the first eight; more decompositions exist.
