Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550146, here are decompositions:

7 + 550139 = 550146
17 + 550129 = 550146
19 + 550127 = 550146
29 + 550117 = 550146
73 + 550073 = 550146
83 + 550063 = 550146
97 + 550049 = 550146
137 + 550009 = 550146

Showing the first eight; more decompositions exist.
