Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551340, here are decompositions:

19 + 551321 = 551340
29 + 551311 = 551340
43 + 551297 = 551340
59 + 551281 = 551340
71 + 551269 = 551340
107 + 551233 = 551340
109 + 551231 = 551340
197 + 551143 = 551340

Showing the first eight; more decompositions exist.
