Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551342, here are decompositions:

3 + 551339 = 551342
31 + 551311 = 551342
61 + 551281 = 551342
73 + 551269 = 551342
109 + 551233 = 551342
163 + 551179 = 551342
199 + 551143 = 551342
229 + 551113 = 551342

Showing the first eight; more decompositions exist.
