Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590658, here are decompositions:

  • 41 + 31590617 = 31590658
  • 101 + 31590557 = 31590658
  • 107 + 31590551 = 31590658
  • 179 + 31590479 = 31590658
  • 191 + 31590467 = 31590658
  • 257 + 31590401 = 31590658
  • 389 + 31590269 = 31590658
  • 509 + 31590149 = 31590658

Showing the first eight; more decompositions exist.
