Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606660, here are decompositions:

  • 3 + 8606657 = 8606660
  • 61 + 8606599 = 8606660
  • 103 + 8606557 = 8606660
  • 151 + 8606509 = 8606660
  • 229 + 8606431 = 8606660
  • 331 + 8606329 = 8606660
  • 367 + 8606293 = 8606660
  • 373 + 8606287 = 8606660

Showing the first eight; more decompositions exist.
