Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700786, here are decompositions:

  • 13 + 8700773 = 8700786
  • 19 + 8700767 = 8700786
  • 89 + 8700697 = 8700786
  • 137 + 8700649 = 8700786
  • 197 + 8700589 = 8700786
  • 223 + 8700563 = 8700786
  • 239 + 8700547 = 8700786
  • 257 + 8700529 = 8700786

Showing the first eight; more decompositions exist.
