Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761806, here are decompositions:

  • 17 + 8761789 = 8761806
  • 43 + 8761763 = 8761806
  • 73 + 8761733 = 8761806
  • 103 + 8761703 = 8761806
  • 167 + 8761639 = 8761806
  • 173 + 8761633 = 8761806
  • 269 + 8761537 = 8761806
  • 337 + 8761469 = 8761806

Showing the first eight; more decompositions exist.
