Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31078, here are decompositions:

  • 59 + 31019 = 31078
  • 101 + 30977 = 31078
  • 107 + 30971 = 31078
  • 137 + 30941 = 31078
  • 167 + 30911 = 31078
  • 197 + 30881 = 31078
  • 227 + 30851 = 31078
  • 239 + 30839 = 31078

Showing the first eight; more decompositions exist.
