Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619710, here are decompositions:

  • 41 + 31619669 = 31619710
  • 107 + 31619603 = 31619710
  • 149 + 31619561 = 31619710
  • 167 + 31619543 = 31619710
  • 179 + 31619531 = 31619710
  • 191 + 31619519 = 31619710
  • 251 + 31619459 = 31619710
  • 383 + 31619327 = 31619710

Showing the first eight; more decompositions exist.
