Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485126, here are decompositions:

5 + 31485121 = 31485126
19 + 31485107 = 31485126
47 + 31485079 = 31485126
59 + 31485067 = 31485126
67 + 31485059 = 31485126
103 + 31485023 = 31485126
107 + 31485019 = 31485126
109 + 31485017 = 31485126

Showing the first eight; more decompositions exist.
