Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551282, here are decompositions:

13 + 551269 = 551282
103 + 551179 = 551282
139 + 551143 = 551282
223 + 551059 = 551282
313 + 550969 = 551282
331 + 550951 = 551282
373 + 550909 = 551282
379 + 550903 = 551282

Showing the first eight; more decompositions exist.
