Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603620, here are decompositions:

17 + 8603603 = 8603620
23 + 8603597 = 8603620
29 + 8603591 = 8603620
41 + 8603579 = 8603620
131 + 8603489 = 8603620
149 + 8603471 = 8603620
167 + 8603453 = 8603620
191 + 8603429 = 8603620

Showing the first eight; more decompositions exist.
