Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466904, here are decompositions:

5 + 31466899 = 31466904
11 + 31466893 = 31466904
31 + 31466873 = 31466904
37 + 31466867 = 31466904
47 + 31466857 = 31466904
83 + 31466821 = 31466904
113 + 31466791 = 31466904
151 + 31466753 = 31466904

Showing the first eight; more decompositions exist.
