Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637498, here are decompositions:

5 + 8637493 = 8637498
7 + 8637491 = 8637498
17 + 8637481 = 8637498
31 + 8637467 = 8637498
47 + 8637451 = 8637498
71 + 8637427 = 8637498
157 + 8637341 = 8637498
179 + 8637319 = 8637498

Showing the first eight; more decompositions exist.
