Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157108, here are decompositions:

  • 5 + 157103 = 157108
  • 47 + 157061 = 157108
  • 59 + 157049 = 157108
  • 71 + 157037 = 157108
  • 89 + 157019 = 157108
  • 101 + 157007 = 157108
  • 137 + 156971 = 157108
  • 167 + 156941 = 157108

Showing the first eight; more decompositions exist.
