Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507044, here are decompositions:

7 + 31507037 = 31507044
67 + 31506977 = 31507044
71 + 31506973 = 31507044
113 + 31506931 = 31507044
137 + 31506907 = 31507044
157 + 31506887 = 31507044
223 + 31506821 = 31507044
251 + 31506793 = 31507044

Showing the first eight; more decompositions exist.
