Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472014, here are decompositions:

3 + 31472011 = 31472014
11 + 31472003 = 31472014
23 + 31471991 = 31472014
47 + 31471967 = 31472014
107 + 31471907 = 31472014
113 + 31471901 = 31472014
131 + 31471883 = 31472014
191 + 31471823 = 31472014

Showing the first eight; more decompositions exist.
