Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747660, here are decompositions:

  • 7 + 8747653 = 8747660
  • 37 + 8747623 = 8747660
  • 43 + 8747617 = 8747660
  • 241 + 8747419 = 8747660
  • 331 + 8747329 = 8747660
  • 409 + 8747251 = 8747660
  • 541 + 8747119 = 8747660
  • 577 + 8747083 = 8747660

Showing the first eight; more decompositions exist.
