Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589352, here are decompositions:

  • 13 + 31589339 = 31589352
  • 19 + 31589333 = 31589352
  • 23 + 31589329 = 31589352
  • 31 + 31589321 = 31589352
  • 59 + 31589293 = 31589352
  • 61 + 31589291 = 31589352
  • 101 + 31589251 = 31589352
  • 233 + 31589119 = 31589352

Showing the first eight; more decompositions exist.
