Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618008, here are decompositions:

17 + 8617991 = 8618008
59 + 8617949 = 8618008
131 + 8617877 = 8618008
137 + 8617871 = 8618008
239 + 8617769 = 8618008
461 + 8617547 = 8618008
569 + 8617439 = 8618008
617 + 8617391 = 8618008

Showing the first eight; more decompositions exist.
