Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551430, here are decompositions:

7 + 551423 = 551430
23 + 551407 = 551430
43 + 551387 = 551430
67 + 551363 = 551430
83 + 551347 = 551430
109 + 551321 = 551430
149 + 551281 = 551430
197 + 551233 = 551430

Showing the first eight; more decompositions exist.
