Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542336, here are decompositions:

13 + 31542323 = 31542336
103 + 31542233 = 31542336
107 + 31542229 = 31542336
139 + 31542197 = 31542336
173 + 31542163 = 31542336
223 + 31542113 = 31542336
233 + 31542103 = 31542336
269 + 31542067 = 31542336

Showing the first eight; more decompositions exist.
