Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686838, here are decompositions:

  • 31 + 8686807 = 8686838
  • 109 + 8686729 = 8686838
  • 151 + 8686687 = 8686838
  • 271 + 8686567 = 8686838
  • 337 + 8686501 = 8686838
  • 367 + 8686471 = 8686838
  • 379 + 8686459 = 8686838
  • 541 + 8686297 = 8686838

Showing the first eight; more decompositions exist.
