Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726220, here are decompositions:

  • 11 + 8726209 = 8726220
  • 17 + 8726203 = 8726220
  • 23 + 8726197 = 8726220
  • 79 + 8726141 = 8726220
  • 127 + 8726093 = 8726220
  • 157 + 8726063 = 8726220
  • 193 + 8726027 = 8726220
  • 199 + 8726021 = 8726220

Showing the first eight; more decompositions exist.
