Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651604, here are decompositions:

23 + 8651581 = 8651604
61 + 8651543 = 8651604
67 + 8651537 = 8651604
97 + 8651507 = 8651604
103 + 8651501 = 8651604
167 + 8651437 = 8651604
251 + 8651353 = 8651604
281 + 8651323 = 8651604

Showing the first eight; more decompositions exist.
