Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725512, here are decompositions:

  • 13 + 8725499 = 8725512
  • 23 + 8725489 = 8725512
  • 31 + 8725481 = 8725512
  • 53 + 8725459 = 8725512
  • 83 + 8725429 = 8725512
  • 113 + 8725399 = 8725512
  • 149 + 8725363 = 8725512
  • 151 + 8725361 = 8725512

Showing the first eight; more decompositions exist.
