Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551582, here are decompositions:

13 + 551569 = 551582
43 + 551539 = 551582
79 + 551503 = 551582
139 + 551443 = 551582
271 + 551311 = 551582
313 + 551269 = 551582
349 + 551233 = 551582
439 + 551143 = 551582

Showing the first eight; more decompositions exist.
