Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449116, here are decompositions:

  • 73 + 31449043 = 31449116
  • 79 + 31449037 = 31449116
  • 277 + 31448839 = 31449116
  • 313 + 31448803 = 31449116
  • 397 + 31448719 = 31449116
  • 409 + 31448707 = 31449116
  • 739 + 31448377 = 31449116
  • 823 + 31448293 = 31449116

Showing the first eight; more decompositions exist.
