Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715530, here are decompositions:

  • 7 + 8715523 = 8715530
  • 79 + 8715451 = 8715530
  • 127 + 8715403 = 8715530
  • 181 + 8715349 = 8715530
  • 193 + 8715337 = 8715530
  • 337 + 8715193 = 8715530
  • 349 + 8715181 = 8715530
  • 379 + 8715151 = 8715530

Showing the first eight; more decompositions exist.
