Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498164, here are decompositions:

13 + 31498151 = 31498164
41 + 31498123 = 31498164
53 + 31498111 = 31498164
157 + 31498007 = 31498164
167 + 31497997 = 31498164
223 + 31497941 = 31498164
233 + 31497931 = 31498164
281 + 31497883 = 31498164

Showing the first eight; more decompositions exist.
