Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636624, here are decompositions:

37 + 8636587 = 8636624
43 + 8636581 = 8636624
103 + 8636521 = 8636624
151 + 8636473 = 8636624
277 + 8636347 = 8636624
457 + 8636167 = 8636624
487 + 8636137 = 8636624
541 + 8636083 = 8636624

Showing the first eight; more decompositions exist.
