Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493158, here are decompositions:

11 + 493147 = 493158
19 + 493139 = 493158
31 + 493127 = 493158
37 + 493121 = 493158
47 + 493111 = 493158
109 + 493049 = 493158
131 + 493027 = 493158
137 + 493021 = 493158

Showing the first eight; more decompositions exist.
