Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617458, here are decompositions:

11 + 8617447 = 8617458
19 + 8617439 = 8617458
41 + 8617417 = 8617458
61 + 8617397 = 8617458
67 + 8617391 = 8617458
97 + 8617361 = 8617458
131 + 8617327 = 8617458
139 + 8617319 = 8617458

Showing the first eight; more decompositions exist.
