Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485048, here are decompositions:

17 + 31485031 = 31485048
29 + 31485019 = 31485048
31 + 31485017 = 31485048
47 + 31485001 = 31485048
59 + 31484989 = 31485048
107 + 31484941 = 31485048
137 + 31484911 = 31485048
211 + 31484837 = 31485048

Showing the first eight; more decompositions exist.
