Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542936, here are decompositions:

  • 59 + 31542877 = 31542936
  • 79 + 31542857 = 31542936
  • 107 + 31542829 = 31542936
  • 109 + 31542827 = 31542936
  • 127 + 31542809 = 31542936
  • 137 + 31542799 = 31542936
  • 149 + 31542787 = 31542936
  • 233 + 31542703 = 31542936

Showing the first eight; more decompositions exist.
