Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577276, here are decompositions:

7 + 31577269 = 31577276
13 + 31577263 = 31577276
37 + 31577239 = 31577276
43 + 31577233 = 31577276
67 + 31577209 = 31577276
79 + 31577197 = 31577276
103 + 31577173 = 31577276
163 + 31577113 = 31577276

Showing the first eight; more decompositions exist.
