Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550188, here are decompositions:

7 + 550181 = 550188
11 + 550177 = 550188
19 + 550169 = 550188
59 + 550129 = 550188
61 + 550127 = 550188
71 + 550117 = 550188
127 + 550061 = 550188
139 + 550049 = 550188

Showing the first eight; more decompositions exist.
