Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447036, here are decompositions:

17 + 31447019 = 31447036
53 + 31446983 = 31447036
83 + 31446953 = 31447036
197 + 31446839 = 31447036
293 + 31446743 = 31447036
347 + 31446689 = 31447036
443 + 31446593 = 31447036
479 + 31446557 = 31447036

Showing the first eight; more decompositions exist.
