Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507050, here are decompositions:

13 + 31507037 = 31507050
41 + 31507009 = 31507050
73 + 31506977 = 31507050
101 + 31506949 = 31507050
139 + 31506911 = 31507050
163 + 31506887 = 31507050
227 + 31506823 = 31507050
229 + 31506821 = 31507050

Showing the first eight; more decompositions exist.
