Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447934, here are decompositions:

3 + 31447931 = 31447934
31 + 31447903 = 31447934
97 + 31447837 = 31447934
151 + 31447783 = 31447934
277 + 31447657 = 31447934
307 + 31447627 = 31447934
457 + 31447477 = 31447934
541 + 31447393 = 31447934

Showing the first eight; more decompositions exist.
