Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729450, here are decompositions:

  • 61 + 8729389 = 8729450
  • 127 + 8729323 = 8729450
  • 211 + 8729239 = 8729450
  • 229 + 8729221 = 8729450
  • 271 + 8729179 = 8729450
  • 277 + 8729173 = 8729450
  • 397 + 8729053 = 8729450
  • 463 + 8728987 = 8729450

Showing the first eight; more decompositions exist.
