Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722206, here are decompositions:

  • 13 + 8722193 = 8722206
  • 19 + 8722187 = 8722206
  • 37 + 8722169 = 8722206
  • 83 + 8722123 = 8722206
  • 89 + 8722117 = 8722206
  • 107 + 8722099 = 8722206
  • 109 + 8722097 = 8722206
  • 113 + 8722093 = 8722206

Showing the first eight; more decompositions exist.
