Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729170, here are decompositions:

  • 29 + 8729141 = 8729170
  • 53 + 8729117 = 8729170
  • 71 + 8729099 = 8729170
  • 89 + 8729081 = 8729170
  • 113 + 8729057 = 8729170
  • 137 + 8729033 = 8729170
  • 227 + 8728943 = 8729170
  • 269 + 8728901 = 8729170

Showing the first eight; more decompositions exist.
