Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629426, here are decompositions:

17 + 8629409 = 8629426
83 + 8629343 = 8629426
227 + 8629199 = 8629426
233 + 8629193 = 8629426
257 + 8629169 = 8629426
269 + 8629157 = 8629426
317 + 8629109 = 8629426
347 + 8629079 = 8629426

Showing the first eight; more decompositions exist.
