Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537052, here are decompositions:

3 + 31537049 = 31537052
13 + 31537039 = 31537052
61 + 31536991 = 31537052
109 + 31536943 = 31537052
181 + 31536871 = 31537052
223 + 31536829 = 31537052
229 + 31536823 = 31537052
439 + 31536613 = 31537052

Showing the first eight; more decompositions exist.
