Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507068, here are decompositions:

31 + 31507037 = 31507068
59 + 31507009 = 31507068
137 + 31506931 = 31507068
139 + 31506929 = 31507068
157 + 31506911 = 31507068
181 + 31506887 = 31507068
227 + 31506841 = 31507068
239 + 31506829 = 31507068

Showing the first eight; more decompositions exist.
