Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616128, here are decompositions:

  • 109 + 8616019 = 8616128
  • 139 + 8615989 = 8616128
  • 211 + 8615917 = 8616128
  • 337 + 8615791 = 8616128
  • 379 + 8615749 = 8616128
  • 421 + 8615707 = 8616128
  • 541 + 8615587 = 8616128
  • 601 + 8615527 = 8616128

Showing the first eight; more decompositions exist.
