Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739218, here are decompositions:

  • 31 + 8739187 = 8739218
  • 139 + 8739079 = 8739218
  • 211 + 8739007 = 8739218
  • 337 + 8738881 = 8739218
  • 379 + 8738839 = 8739218
  • 409 + 8738809 = 8739218
  • 547 + 8738671 = 8739218
  • 577 + 8738641 = 8739218

Showing the first eight; more decompositions exist.
