Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449252, here are decompositions:

5 + 31449247 = 31449252
11 + 31449241 = 31449252
19 + 31449233 = 31449252
61 + 31449191 = 31449252
73 + 31449179 = 31449252
89 + 31449163 = 31449252
181 + 31449071 = 31449252
199 + 31449053 = 31449252

Showing the first eight; more decompositions exist.
