Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687042, here are decompositions:

  • 43 + 8686999 = 8687042
  • 61 + 8686981 = 8687042
  • 313 + 8686729 = 8687042
  • 373 + 8686669 = 8687042
  • 541 + 8686501 = 8687042
  • 571 + 8686471 = 8687042
  • 673 + 8686369 = 8687042
  • 733 + 8686309 = 8687042

Showing the first eight; more decompositions exist.
