Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717390, here are decompositions:

37 + 8717353 = 8717390
61 + 8717329 = 8717390
67 + 8717323 = 8717390
103 + 8717287 = 8717390
127 + 8717263 = 8717390
151 + 8717239 = 8717390
271 + 8717119 = 8717390
277 + 8717113 = 8717390

Showing the first eight; more decompositions exist.
