Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663870, here are decompositions:

  • 43 + 8663827 = 8663870
  • 67 + 8663803 = 8663870
  • 73 + 8663797 = 8663870
  • 151 + 8663719 = 8663870
  • 277 + 8663593 = 8663870
  • 349 + 8663521 = 8663870
  • 367 + 8663503 = 8663870
  • 373 + 8663497 = 8663870

Showing the first eight; more decompositions exist.
