Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651402, here are decompositions:

3 + 8651399 = 8651402
13 + 8651389 = 8651402
43 + 8651359 = 8651402
73 + 8651329 = 8651402
79 + 8651323 = 8651402
163 + 8651239 = 8651402
211 + 8651191 = 8651402
223 + 8651179 = 8651402

Showing the first eight; more decompositions exist.
