Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627858, here are decompositions:

  • 7 + 8627851 = 8627858
  • 157 + 8627701 = 8627858
  • 241 + 8627617 = 8627858
  • 277 + 8627581 = 8627858
  • 331 + 8627527 = 8627858
  • 487 + 8627371 = 8627858
  • 601 + 8627257 = 8627858
  • 607 + 8627251 = 8627858

Showing the first eight; more decompositions exist.
