Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466142, here are decompositions:

5 + 31466137 = 31466142
23 + 31466119 = 31466142
41 + 31466101 = 31466142
53 + 31466089 = 31466142
79 + 31466063 = 31466142
89 + 31466053 = 31466142
139 + 31466003 = 31466142
163 + 31465979 = 31466142

Showing the first eight; more decompositions exist.
