Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729188, here are decompositions:

  • 5 + 8729183 = 8729188
  • 47 + 8729141 = 8729188
  • 71 + 8729117 = 8729188
  • 89 + 8729099 = 8729188
  • 107 + 8729081 = 8729188
  • 131 + 8729057 = 8729188
  • 137 + 8729051 = 8729188
  • 401 + 8728787 = 8729188

Showing the first eight; more decompositions exist.
