Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683390, here are decompositions:

59 + 8683331 = 8683390
71 + 8683319 = 8683390
83 + 8683307 = 8683390
137 + 8683253 = 8683390
167 + 8683223 = 8683390
173 + 8683217 = 8683390
227 + 8683163 = 8683390
293 + 8683097 = 8683390

Showing the first eight; more decompositions exist.
