Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615560, here are decompositions:

  • 17 + 8615543 = 8615560
  • 47 + 8615513 = 8615560
  • 53 + 8615507 = 8615560
  • 89 + 8615471 = 8615560
  • 137 + 8615423 = 8615560
  • 227 + 8615333 = 8615560
  • 281 + 8615279 = 8615560
  • 293 + 8615267 = 8615560

Showing the first eight; more decompositions exist.
