Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632390, here are decompositions:

3 + 8632387 = 8632390
23 + 8632367 = 8632390
29 + 8632361 = 8632390
167 + 8632223 = 8632390
233 + 8632157 = 8632390
251 + 8632139 = 8632390
257 + 8632133 = 8632390
479 + 8631911 = 8632390

Showing the first eight; more decompositions exist.
