Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637358, here are decompositions:

17 + 8637341 = 8637358
47 + 8637311 = 8637358
101 + 8637257 = 8637358
131 + 8637227 = 8637358
179 + 8637179 = 8637358
227 + 8637131 = 8637358
239 + 8637119 = 8637358
251 + 8637107 = 8637358

Showing the first eight; more decompositions exist.
