Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651556, here are decompositions:

7 + 8651549 = 8651556
13 + 8651543 = 8651556
19 + 8651537 = 8651556
97 + 8651459 = 8651556
113 + 8651443 = 8651556
127 + 8651429 = 8651556
157 + 8651399 = 8651556
167 + 8651389 = 8651556

Showing the first eight; more decompositions exist.
