Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551252, here are decompositions:

19 + 551233 = 551252
73 + 551179 = 551252
109 + 551143 = 551252
139 + 551113 = 551252
193 + 551059 = 551252
283 + 550969 = 551252
313 + 550939 = 551252
349 + 550903 = 551252

Showing the first eight; more decompositions exist.
