Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542162, here are decompositions:

13 + 31542149 = 31542162
59 + 31542103 = 31542162
79 + 31542083 = 31542162
131 + 31542031 = 31542162
139 + 31542023 = 31542162
149 + 31542013 = 31542162
151 + 31542011 = 31542162
173 + 31541989 = 31542162

Showing the first eight; more decompositions exist.
