Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7790, here are decompositions:

  • 31 + 7759 = 7790
  • 37 + 7753 = 7790
  • 67 + 7723 = 7790
  • 73 + 7717 = 7790
  • 103 + 7687 = 7790
  • 109 + 7681 = 7790
  • 151 + 7639 = 7790
  • 199 + 7591 = 7790

Showing the first eight; more decompositions exist.
