Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564246, here are decompositions:

3 + 31564243 = 31564246
5 + 31564241 = 31564246
17 + 31564229 = 31564246
83 + 31564163 = 31564246
89 + 31564157 = 31564246
107 + 31564139 = 31564246
113 + 31564133 = 31564246
167 + 31564079 = 31564246

Showing the first eight; more decompositions exist.
