Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637522, here are decompositions:

13 + 8637509 = 8637522
29 + 8637493 = 8637522
31 + 8637491 = 8637522
41 + 8637481 = 8637522
71 + 8637451 = 8637522
73 + 8637449 = 8637522
149 + 8637373 = 8637522
181 + 8637341 = 8637522

Showing the first eight; more decompositions exist.
