Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625390, here are decompositions:

  • 31 + 8625359 = 8625390
  • 41 + 8625349 = 8625390
  • 47 + 8625343 = 8625390
  • 73 + 8625317 = 8625390
  • 79 + 8625311 = 8625390
  • 89 + 8625301 = 8625390
  • 101 + 8625289 = 8625390
  • 127 + 8625263 = 8625390

Showing the first eight; more decompositions exist.
