Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465194, here are decompositions:

11 + 31465183 = 31465194
17 + 31465177 = 31465194
41 + 31465153 = 31465194
71 + 31465123 = 31465194
83 + 31465111 = 31465194
191 + 31465003 = 31465194
227 + 31464967 = 31465194
311 + 31464883 = 31465194

Showing the first eight; more decompositions exist.
