Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465008, here are decompositions:

5 + 31465003 = 31465008
17 + 31464991 = 31465008
41 + 31464967 = 31465008
61 + 31464947 = 31465008
67 + 31464941 = 31465008
181 + 31464827 = 31465008
199 + 31464809 = 31465008
227 + 31464781 = 31465008

Showing the first eight; more decompositions exist.
