Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485060, here are decompositions:

11 + 31485049 = 31485060
29 + 31485031 = 31485060
37 + 31485023 = 31485060
41 + 31485019 = 31485060
43 + 31485017 = 31485060
59 + 31485001 = 31485060
67 + 31484993 = 31485060
71 + 31484989 = 31485060

Showing the first eight; more decompositions exist.
