Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617942, here are decompositions:

  • 71 + 8617871 = 8617942
  • 173 + 8617769 = 8617942
  • 239 + 8617703 = 8617942
  • 419 + 8617523 = 8617942
  • 503 + 8617439 = 8617942
  • 569 + 8617373 = 8617942
  • 941 + 8617001 = 8617942
  • 953 + 8616989 = 8617942

Showing the first eight; more decompositions exist.
