Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465196, here are decompositions:

3 + 31465193 = 31465196
13 + 31465183 = 31465196
19 + 31465177 = 31465196
43 + 31465153 = 31465196
67 + 31465129 = 31465196
73 + 31465123 = 31465196
97 + 31465099 = 31465196
127 + 31465069 = 31465196

Showing the first eight; more decompositions exist.
