Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507222, here are decompositions:

11 + 31507211 = 31507222
23 + 31507199 = 31507222
41 + 31507181 = 31507222
83 + 31507139 = 31507222
113 + 31507109 = 31507222
293 + 31506929 = 31507222
311 + 31506911 = 31507222
401 + 31506821 = 31507222

Showing the first eight; more decompositions exist.
