Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617390, here are decompositions:

17 + 8617373 = 8617390
29 + 8617361 = 8617390
71 + 8617319 = 8617390
113 + 8617277 = 8617390
137 + 8617253 = 8617390
179 + 8617211 = 8617390
281 + 8617109 = 8617390
293 + 8617097 = 8617390

Showing the first eight; more decompositions exist.
