Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507092, here are decompositions:

5 + 31507087 = 31507092
11 + 31507081 = 31507092
83 + 31507009 = 31507092
163 + 31506929 = 31507092
181 + 31506911 = 31507092
251 + 31506841 = 31507092
263 + 31506829 = 31507092
269 + 31506823 = 31507092

Showing the first eight; more decompositions exist.
