Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637492, here are decompositions:

11 + 8637481 = 8637492
41 + 8637451 = 8637492
43 + 8637449 = 8637492
113 + 8637379 = 8637492
151 + 8637341 = 8637492
173 + 8637319 = 8637492
181 + 8637311 = 8637492
191 + 8637301 = 8637492

Showing the first eight; more decompositions exist.
