Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551672, here are decompositions:

13 + 551659 = 551672
19 + 551653 = 551672
103 + 551569 = 551672
211 + 551461 = 551672
229 + 551443 = 551672
439 + 551233 = 551672
613 + 551059 = 551672
733 + 550939 = 551672

Showing the first eight; more decompositions exist.
