Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550228, here are decompositions:

17 + 550211 = 550228
47 + 550181 = 550228
59 + 550169 = 550228
89 + 550139 = 550228
101 + 550127 = 550228
167 + 550061 = 550228
179 + 550049 = 550228
251 + 549977 = 550228

Showing the first eight; more decompositions exist.
