Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651406, here are decompositions:

7 + 8651399 = 8651406
17 + 8651389 = 8651406
47 + 8651359 = 8651406
53 + 8651353 = 8651406
83 + 8651323 = 8651406
109 + 8651297 = 8651406
139 + 8651267 = 8651406
167 + 8651239 = 8651406

Showing the first eight; more decompositions exist.
