Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056, here are decompositions:

  • 5 + 1051 = 1056
  • 7 + 1049 = 1056
  • 17 + 1039 = 1056
  • 23 + 1033 = 1056
  • 37 + 1019 = 1056
  • 43 + 1013 = 1056
  • 47 + 1009 = 1056
  • 59 + 997 = 1056

Showing the first eight; more decompositions exist.
