Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1078, here are decompositions:

  • 17 + 1061 = 1078
  • 29 + 1049 = 1078
  • 47 + 1031 = 1078
  • 59 + 1019 = 1078
  • 101 + 977 = 1078
  • 107 + 971 = 1078
  • 131 + 947 = 1078
  • 137 + 941 = 1078

Showing the first eight; more decompositions exist.
