Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637770, here are decompositions:

  • 73 + 8637697 = 8637770
  • 103 + 8637667 = 8637770
  • 151 + 8637619 = 8637770
  • 277 + 8637493 = 8637770
  • 397 + 8637373 = 8637770
  • 433 + 8637337 = 8637770
  • 523 + 8637247 = 8637770
  • 607 + 8637163 = 8637770

Showing the first eight; more decompositions exist.
