Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603646, here are decompositions:

43 + 8603603 = 8603646
53 + 8603593 = 8603646
67 + 8603579 = 8603646
113 + 8603533 = 8603646
137 + 8603509 = 8603646
157 + 8603489 = 8603646
179 + 8603467 = 8603646
193 + 8603453 = 8603646

Showing the first eight; more decompositions exist.
