Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551450, here are decompositions:

7 + 551443 = 551450
43 + 551407 = 551450
103 + 551347 = 551450
139 + 551311 = 551450
181 + 551269 = 551450
271 + 551179 = 551450
307 + 551143 = 551450
337 + 551113 = 551450

Showing the first eight; more decompositions exist.
