Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551620, here are decompositions:

23 + 551597 = 551620
71 + 551549 = 551620
101 + 551519 = 551620
131 + 551489 = 551620
137 + 551483 = 551620
197 + 551423 = 551620
233 + 551387 = 551620
239 + 551381 = 551620

Showing the first eight; more decompositions exist.
