Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471302, here are decompositions:

13 + 31471289 = 31471302
89 + 31471213 = 31471302
131 + 31471171 = 31471302
179 + 31471123 = 31471302
193 + 31471109 = 31471302
211 + 31471091 = 31471302
223 + 31471079 = 31471302
251 + 31471051 = 31471302

Showing the first eight; more decompositions exist.
