Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485124, here are decompositions:

3 + 31485121 = 31485124
17 + 31485107 = 31485124
23 + 31485101 = 31485124
101 + 31485023 = 31485124
107 + 31485017 = 31485124
131 + 31484993 = 31485124
347 + 31484777 = 31485124
353 + 31484771 = 31485124

Showing the first eight; more decompositions exist.
