Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447914, here are decompositions:

11 + 31447903 = 31447914
13 + 31447901 = 31447914
61 + 31447853 = 31447914
101 + 31447813 = 31447914
103 + 31447811 = 31447914
131 + 31447783 = 31447914
163 + 31447751 = 31447914
233 + 31447681 = 31447914

Showing the first eight; more decompositions exist.
