Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551624, here are decompositions:

37 + 551587 = 551624
43 + 551581 = 551624
67 + 551557 = 551624
163 + 551461 = 551624
181 + 551443 = 551624
277 + 551347 = 551624
313 + 551311 = 551624
607 + 551017 = 551624

Showing the first eight; more decompositions exist.
