Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651804, here are decompositions:

13 + 8651791 = 8651804
67 + 8651737 = 8651804
157 + 8651647 = 8651804
223 + 8651581 = 8651804
367 + 8651437 = 8651804
523 + 8651281 = 8651804
571 + 8651233 = 8651804
613 + 8651191 = 8651804

Showing the first eight; more decompositions exist.
