Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672436, here are decompositions:

  • 7 + 8672429 = 8672436
  • 13 + 8672423 = 8672436
  • 29 + 8672407 = 8672436
  • 83 + 8672353 = 8672436
  • 89 + 8672347 = 8672436
  • 103 + 8672333 = 8672436
  • 139 + 8672297 = 8672436
  • 163 + 8672273 = 8672436

Showing the first eight; more decompositions exist.
