Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563766, here are decompositions:

29 + 31563737 = 31563766
83 + 31563683 = 31563766
173 + 31563593 = 31563766
197 + 31563569 = 31563766
239 + 31563527 = 31563766
389 + 31563377 = 31563766
419 + 31563347 = 31563766
557 + 31563209 = 31563766

Showing the first eight; more decompositions exist.
