Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551156, here are decompositions:

13 + 551143 = 551156
43 + 551113 = 551156
97 + 551059 = 551156
139 + 551017 = 551156
163 + 550993 = 551156
313 + 550843 = 551156
367 + 550789 = 551156
439 + 550717 = 551156

Showing the first eight; more decompositions exist.
