Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1064, here are decompositions:

  • 3 + 1061 = 1064
  • 13 + 1051 = 1064
  • 31 + 1033 = 1064
  • 43 + 1021 = 1064
  • 67 + 997 = 1064
  • 73 + 991 = 1064
  • 97 + 967 = 1064
  • 127 + 937 = 1064

Showing the first eight; more decompositions exist.
