Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447034, here are decompositions:

7 + 31447027 = 31447034
13 + 31447021 = 31447034
37 + 31446997 = 31447034
61 + 31446973 = 31447034
97 + 31446937 = 31447034
163 + 31446871 = 31447034
181 + 31446853 = 31447034
277 + 31446757 = 31447034

Showing the first eight; more decompositions exist.
