Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550218, here are decompositions:

5 + 550213 = 550218
7 + 550211 = 550218
29 + 550189 = 550218
37 + 550181 = 550218
41 + 550177 = 550218
79 + 550139 = 550218
89 + 550129 = 550218
101 + 550117 = 550218

Showing the first eight; more decompositions exist.
