Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632290, here are decompositions:

11 + 8632279 = 8632290
53 + 8632237 = 8632290
67 + 8632223 = 8632290
71 + 8632219 = 8632290
103 + 8632187 = 8632290
151 + 8632139 = 8632290
157 + 8632133 = 8632290
167 + 8632123 = 8632290

Showing the first eight; more decompositions exist.
