Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551660, here are decompositions:

7 + 551653 = 551660
73 + 551587 = 551660
79 + 551581 = 551660
103 + 551557 = 551660
157 + 551503 = 551660
199 + 551461 = 551660
313 + 551347 = 551660
349 + 551311 = 551660

Showing the first eight; more decompositions exist.
