Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651418, here are decompositions:

19 + 8651399 = 8651418
29 + 8651389 = 8651418
59 + 8651359 = 8651418
89 + 8651329 = 8651418
107 + 8651311 = 8651418
137 + 8651281 = 8651418
151 + 8651267 = 8651418
157 + 8651261 = 8651418

Showing the first eight; more decompositions exist.
