Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726280, here are decompositions:

  • 7 + 8726273 = 8726280
  • 23 + 8726257 = 8726280
  • 37 + 8726243 = 8726280
  • 41 + 8726239 = 8726280
  • 53 + 8726227 = 8726280
  • 71 + 8726209 = 8726280
  • 83 + 8726197 = 8726280
  • 137 + 8726143 = 8726280

Showing the first eight; more decompositions exist.
