Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024, here are decompositions:

  • 3 + 1021 = 1024
  • 5 + 1019 = 1024
  • 11 + 1013 = 1024
  • 41 + 983 = 1024
  • 47 + 977 = 1024
  • 53 + 971 = 1024
  • 71 + 953 = 1024
  • 83 + 941 = 1024

Showing the first eight; more decompositions exist.
