Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651394, here are decompositions:

5 + 8651389 = 8651394
41 + 8651353 = 8651394
71 + 8651323 = 8651394
83 + 8651311 = 8651394
97 + 8651297 = 8651394
113 + 8651281 = 8651394
127 + 8651267 = 8651394
163 + 8651231 = 8651394

Showing the first eight; more decompositions exist.
