Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507012, here are decompositions:

3 + 31507009 = 31507012
83 + 31506929 = 31507012
101 + 31506911 = 31507012
191 + 31506821 = 31507012
263 + 31506749 = 31507012
269 + 31506743 = 31507012
293 + 31506719 = 31507012
443 + 31506569 = 31507012

Showing the first eight; more decompositions exist.
