Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645624, here are decompositions:

7 + 8645617 = 8645624
37 + 8645587 = 8645624
181 + 8645443 = 8645624
193 + 8645431 = 8645624
271 + 8645353 = 8645624
283 + 8645341 = 8645624
331 + 8645293 = 8645624
367 + 8645257 = 8645624

Showing the first eight; more decompositions exist.
