Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542166, here are decompositions:

3 + 31542163 = 31542166
17 + 31542149 = 31542166
53 + 31542113 = 31542166
83 + 31542083 = 31542166
233 + 31541933 = 31542166
263 + 31541903 = 31542166
569 + 31541597 = 31542166
659 + 31541507 = 31542166

Showing the first eight; more decompositions exist.
