Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507062, here are decompositions:

53 + 31507009 = 31507062
89 + 31506973 = 31507062
113 + 31506949 = 31507062
131 + 31506931 = 31507062
151 + 31506911 = 31507062
233 + 31506829 = 31507062
239 + 31506823 = 31507062
241 + 31506821 = 31507062

Showing the first eight; more decompositions exist.
