Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447576, here are decompositions:

3 + 31447573 = 31447576
47 + 31447529 = 31447576
89 + 31447487 = 31447576
137 + 31447439 = 31447576
197 + 31447379 = 31447576
359 + 31447217 = 31447576
443 + 31447133 = 31447576
557 + 31447019 = 31447576

Showing the first eight; more decompositions exist.
