Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550172, here are decompositions:

3 + 550169 = 550172
43 + 550129 = 550172
61 + 550111 = 550172
109 + 550063 = 550172
163 + 550009 = 550172
193 + 549979 = 550172
223 + 549949 = 550172
229 + 549943 = 550172

Showing the first eight; more decompositions exist.
