Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485054, here are decompositions:

5 + 31485049 = 31485054
23 + 31485031 = 31485054
31 + 31485023 = 31485054
37 + 31485017 = 31485054
53 + 31485001 = 31485054
61 + 31484993 = 31485054
113 + 31484941 = 31485054
151 + 31484903 = 31485054

Showing the first eight; more decompositions exist.
