Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506952, here are decompositions:

3 + 31506949 = 31506952
23 + 31506929 = 31506952
41 + 31506911 = 31506952
131 + 31506821 = 31506952
233 + 31506719 = 31506952
263 + 31506689 = 31506952
311 + 31506641 = 31506952
353 + 31506599 = 31506952

Showing the first eight; more decompositions exist.
