Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715490, here are decompositions:

  • 41 + 8715449 = 8715490
  • 59 + 8715431 = 8715490
  • 89 + 8715401 = 8715490
  • 107 + 8715383 = 8715490
  • 167 + 8715323 = 8715490
  • 227 + 8715263 = 8715490
  • 257 + 8715233 = 8715490
  • 281 + 8715209 = 8715490

Showing the first eight; more decompositions exist.
