Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463202, here are decompositions:

5 + 31463197 = 31463202
41 + 31463161 = 31463202
79 + 31463123 = 31463202
103 + 31463099 = 31463202
139 + 31463063 = 31463202
179 + 31463023 = 31463202
223 + 31462979 = 31463202
233 + 31462969 = 31463202

Showing the first eight; more decompositions exist.
