Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551312, here are decompositions:

31 + 551281 = 551312
43 + 551269 = 551312
79 + 551233 = 551312
199 + 551113 = 551312
373 + 550939 = 551312
409 + 550903 = 551312
499 + 550813 = 551312
523 + 550789 = 551312

Showing the first eight; more decompositions exist.
