Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651358, here are decompositions:

5 + 8651353 = 8651358
29 + 8651329 = 8651358
47 + 8651311 = 8651358
61 + 8651297 = 8651358
97 + 8651261 = 8651358
127 + 8651231 = 8651358
151 + 8651207 = 8651358
167 + 8651191 = 8651358

Showing the first eight; more decompositions exist.
