Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551516, here are decompositions:

13 + 551503 = 551516
73 + 551443 = 551516
109 + 551407 = 551516
283 + 551233 = 551516
337 + 551179 = 551516
373 + 551143 = 551516
409 + 551107 = 551516
457 + 551059 = 551516

Showing the first eight; more decompositions exist.
