Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466196, here are decompositions:

23 + 31466173 = 31466196
53 + 31466143 = 31466196
59 + 31466137 = 31466196
89 + 31466107 = 31466196
107 + 31466089 = 31466196
193 + 31466003 = 31466196
197 + 31465999 = 31466196
317 + 31465879 = 31466196

Showing the first eight; more decompositions exist.
