Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651478, here are decompositions:

19 + 8651459 = 8651478
41 + 8651437 = 8651478
79 + 8651399 = 8651478
89 + 8651389 = 8651478
149 + 8651329 = 8651478
167 + 8651311 = 8651478
181 + 8651297 = 8651478
197 + 8651281 = 8651478

Showing the first eight; more decompositions exist.
