Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551238, here are decompositions:

5 + 551233 = 551238
7 + 551231 = 551238
19 + 551219 = 551238
31 + 551207 = 551238
41 + 551197 = 551238
59 + 551179 = 551238
109 + 551129 = 551238
131 + 551107 = 551238

Showing the first eight; more decompositions exist.
