Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550242, here are decompositions:

29 + 550213 = 550242
31 + 550211 = 550242
53 + 550189 = 550242
61 + 550181 = 550242
73 + 550169 = 550242
79 + 550163 = 550242
103 + 550139 = 550242
113 + 550129 = 550242

Showing the first eight; more decompositions exist.
