Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603644, here are decompositions:

41 + 8603603 = 8603644
47 + 8603597 = 8603644
53 + 8603591 = 8603644
167 + 8603477 = 8603644
173 + 8603471 = 8603644
191 + 8603453 = 8603644
251 + 8603393 = 8603644
263 + 8603381 = 8603644

Showing the first eight; more decompositions exist.
