Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629390, here are decompositions:

41 + 8629349 = 8629390
47 + 8629343 = 8629390
149 + 8629241 = 8629390
191 + 8629199 = 8629390
197 + 8629193 = 8629390
233 + 8629157 = 8629390
251 + 8629139 = 8629390
281 + 8629109 = 8629390

Showing the first eight; more decompositions exist.
