Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551270, here are decompositions:

37 + 551233 = 551270
73 + 551197 = 551270
127 + 551143 = 551270
157 + 551113 = 551270
163 + 551107 = 551270
211 + 551059 = 551270
277 + 550993 = 551270
331 + 550939 = 551270

Showing the first eight; more decompositions exist.
