Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637524, here are decompositions:

3 + 8637521 = 8637524
31 + 8637493 = 8637524
43 + 8637481 = 8637524
73 + 8637451 = 8637524
97 + 8637427 = 8637524
151 + 8637373 = 8637524
223 + 8637301 = 8637524
271 + 8637253 = 8637524

Showing the first eight; more decompositions exist.
