Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726340, here are decompositions:

  • 11 + 8726329 = 8726340
  • 17 + 8726323 = 8726340
  • 67 + 8726273 = 8726340
  • 83 + 8726257 = 8726340
  • 97 + 8726243 = 8726340
  • 101 + 8726239 = 8726340
  • 113 + 8726227 = 8726340
  • 131 + 8726209 = 8726340

Showing the first eight; more decompositions exist.
