Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609990, here are decompositions:

3 + 8609987 = 8609990
73 + 8609917 = 8609990
79 + 8609911 = 8609990
157 + 8609833 = 8609990
199 + 8609791 = 8609990
271 + 8609719 = 8609990
307 + 8609683 = 8609990
313 + 8609677 = 8609990

Showing the first eight; more decompositions exist.
