Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747656, here are decompositions:

  • 3 + 8747653 = 8747656
  • 53 + 8747603 = 8747656
  • 83 + 8747573 = 8747656
  • 167 + 8747489 = 8747656
  • 173 + 8747483 = 8747656
  • 233 + 8747423 = 8747656
  • 383 + 8747273 = 8747656
  • 443 + 8747213 = 8747656

Showing the first eight; more decompositions exist.
