Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030, here are decompositions:

  • 11 + 1019 = 1030
  • 17 + 1013 = 1030
  • 47 + 983 = 1030
  • 53 + 977 = 1030
  • 59 + 971 = 1030
  • 83 + 947 = 1030
  • 89 + 941 = 1030
  • 101 + 929 = 1030

Showing the first eight; more decompositions exist.
