Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645852, here are decompositions:

3 + 8645849 = 8645852
79 + 8645773 = 8645852
199 + 8645653 = 8645852
409 + 8645443 = 8645852
421 + 8645431 = 8645852
499 + 8645353 = 8645852
571 + 8645281 = 8645852
613 + 8645239 = 8645852

Showing the first eight; more decompositions exist.
