Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563246, here are decompositions:

37 + 31563209 = 31563246
53 + 31563193 = 31563246
59 + 31563187 = 31563246
83 + 31563163 = 31563246
97 + 31563149 = 31563246
109 + 31563137 = 31563246
157 + 31563089 = 31563246
173 + 31563073 = 31563246

Showing the first eight; more decompositions exist.
