Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651744, here are decompositions:

7 + 8651737 = 8651744
61 + 8651683 = 8651744
97 + 8651647 = 8651744
163 + 8651581 = 8651744
307 + 8651437 = 8651744
421 + 8651323 = 8651744
433 + 8651311 = 8651744
463 + 8651281 = 8651744

Showing the first eight; more decompositions exist.
