Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551618, here are decompositions:

31 + 551587 = 551618
37 + 551581 = 551618
61 + 551557 = 551618
79 + 551539 = 551618
157 + 551461 = 551618
211 + 551407 = 551618
271 + 551347 = 551618
307 + 551311 = 551618

Showing the first eight; more decompositions exist.
