Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551656, here are decompositions:

3 + 551653 = 551656
5 + 551651 = 551656
59 + 551597 = 551656
107 + 551549 = 551656
113 + 551543 = 551656
137 + 551519 = 551656
167 + 551489 = 551656
173 + 551483 = 551656

Showing the first eight; more decompositions exist.
