Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600620, here are decompositions:

  • 71 + 31600549 = 31600620
  • 89 + 31600531 = 31600620
  • 97 + 31600523 = 31600620
  • 109 + 31600511 = 31600620
  • 127 + 31600493 = 31600620
  • 167 + 31600453 = 31600620
  • 173 + 31600447 = 31600620
  • 179 + 31600441 = 31600620

Showing the first eight; more decompositions exist.
