Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551284, here are decompositions:

3 + 551281 = 551284
53 + 551231 = 551284
191 + 551093 = 551284
257 + 551027 = 551284
281 + 551003 = 551284
311 + 550973 = 551284
347 + 550937 = 551284
443 + 550841 = 551284

Showing the first eight; more decompositions exist.
