Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466112, here are decompositions:

5 + 31466107 = 31466112
11 + 31466101 = 31466112
23 + 31466089 = 31466112
59 + 31466053 = 31466112
61 + 31466051 = 31466112
109 + 31466003 = 31466112
113 + 31465999 = 31466112
233 + 31465879 = 31466112

Showing the first eight; more decompositions exist.
