Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637044, here are decompositions:

37 + 8637007 = 8637044
127 + 8636917 = 8637044
151 + 8636893 = 8637044
307 + 8636737 = 8637044
331 + 8636713 = 8637044
373 + 8636671 = 8637044
397 + 8636647 = 8637044
457 + 8636587 = 8637044

Showing the first eight; more decompositions exist.
