Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026, here are decompositions:

  • 5 + 1021 = 1026
  • 7 + 1019 = 1026
  • 13 + 1013 = 1026
  • 17 + 1009 = 1026
  • 29 + 997 = 1026
  • 43 + 983 = 1026
  • 59 + 967 = 1026
  • 73 + 953 = 1026

Showing the first eight; more decompositions exist.
