Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673940, here are decompositions:

  • 17 + 8673923 = 8673940
  • 29 + 8673911 = 8673940
  • 101 + 8673839 = 8673940
  • 179 + 8673761 = 8673940
  • 257 + 8673683 = 8673940
  • 263 + 8673677 = 8673940
  • 347 + 8673593 = 8673940
  • 521 + 8673419 = 8673940

Showing the first eight; more decompositions exist.
