Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507052, here are decompositions:

43 + 31507009 = 31507052
79 + 31506973 = 31507052
103 + 31506949 = 31507052
211 + 31506841 = 31507052
223 + 31506829 = 31507052
229 + 31506823 = 31507052
271 + 31506781 = 31507052
523 + 31506529 = 31507052

Showing the first eight; more decompositions exist.
