Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551478, here are decompositions:

17 + 551461 = 551478
71 + 551407 = 551478
97 + 551381 = 551478
131 + 551347 = 551478
139 + 551339 = 551478
157 + 551321 = 551478
167 + 551311 = 551478
181 + 551297 = 551478

Showing the first eight; more decompositions exist.
