Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71792, here are decompositions:

  • 3 + 71789 = 71792
  • 31 + 71761 = 71792
  • 73 + 71719 = 71792
  • 79 + 71713 = 71792
  • 199 + 71593 = 71792
  • 223 + 71569 = 71792
  • 229 + 71563 = 71792
  • 241 + 71551 = 71792

Showing the first eight; more decompositions exist.
