Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637222, here are decompositions:

19 + 8637203 = 8637222
43 + 8637179 = 8637222
59 + 8637163 = 8637222
71 + 8637151 = 8637222
89 + 8637133 = 8637222
103 + 8637119 = 8637222
131 + 8637091 = 8637222
163 + 8637059 = 8637222

Showing the first eight; more decompositions exist.
