Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465134, here are decompositions:

5 + 31465129 = 31465134
11 + 31465123 = 31465134
23 + 31465111 = 31465134
73 + 31465061 = 31465134
101 + 31465033 = 31465134
131 + 31465003 = 31465134
167 + 31464967 = 31465134
193 + 31464941 = 31465134

Showing the first eight; more decompositions exist.
