Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498014, here are decompositions:

5 + 31498009 = 31498014
7 + 31498007 = 31498014
11 + 31498003 = 31498014
17 + 31497997 = 31498014
73 + 31497941 = 31498014
83 + 31497931 = 31498014
131 + 31497883 = 31498014
151 + 31497863 = 31498014

Showing the first eight; more decompositions exist.
