Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482810, here are decompositions:

  • 11 + 31482799 = 31482810
  • 31 + 31482779 = 31482810
  • 67 + 31482743 = 31482810
  • 101 + 31482709 = 31482810
  • 103 + 31482707 = 31482810
  • 127 + 31482683 = 31482810
  • 167 + 31482643 = 31482810
  • 179 + 31482631 = 31482810

Showing the first eight; more decompositions exist.
