Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729646, here are decompositions:

  • 5 + 8729641 = 8729646
  • 17 + 8729629 = 8729646
  • 43 + 8729603 = 8729646
  • 53 + 8729593 = 8729646
  • 83 + 8729563 = 8729646
  • 89 + 8729557 = 8729646
  • 103 + 8729543 = 8729646
  • 179 + 8729467 = 8729646

Showing the first eight; more decompositions exist.
