Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465146, here are decompositions:

17 + 31465129 = 31465146
23 + 31465123 = 31465146
47 + 31465099 = 31465146
107 + 31465039 = 31465146
113 + 31465033 = 31465146
173 + 31464973 = 31465146
179 + 31464967 = 31465146
199 + 31464947 = 31465146

Showing the first eight; more decompositions exist.
