Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712680, here are decompositions:

  • 3 + 8712677 = 8712680
  • 19 + 8712661 = 8712680
  • 79 + 8712601 = 8712680
  • 103 + 8712577 = 8712680
  • 157 + 8712523 = 8712680
  • 283 + 8712397 = 8712680
  • 307 + 8712373 = 8712680
  • 313 + 8712367 = 8712680

Showing the first eight; more decompositions exist.
