Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742266, here are decompositions:

  • 3 + 8742263 = 8742266
  • 7 + 8742259 = 8742266
  • 73 + 8742193 = 8742266
  • 79 + 8742187 = 8742266
  • 97 + 8742169 = 8742266
  • 109 + 8742157 = 8742266
  • 163 + 8742103 = 8742266
  • 199 + 8742067 = 8742266

Showing the first eight; more decompositions exist.
