Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550142, here are decompositions:

3 + 550139 = 550142
13 + 550129 = 550142
31 + 550111 = 550142
79 + 550063 = 550142
163 + 549979 = 550142
193 + 549949 = 550142
199 + 549943 = 550142
409 + 549733 = 550142

Showing the first eight; more decompositions exist.
