Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617918, here are decompositions:

41 + 8617877 = 8617918
47 + 8617871 = 8617918
131 + 8617787 = 8617918
149 + 8617769 = 8617918
479 + 8617439 = 8617918
521 + 8617397 = 8617918
557 + 8617361 = 8617918
599 + 8617319 = 8617918

Showing the first eight; more decompositions exist.
