Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542234, here are decompositions:

5 + 31542229 = 31542234
37 + 31542197 = 31542234
71 + 31542163 = 31542234
131 + 31542103 = 31542234
151 + 31542083 = 31542234
167 + 31542067 = 31542234
197 + 31542037 = 31542234
211 + 31542023 = 31542234

Showing the first eight; more decompositions exist.
