Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569956, here are decompositions:

3 + 31569953 = 31569956
13 + 31569943 = 31569956
73 + 31569883 = 31569956
97 + 31569859 = 31569956
127 + 31569829 = 31569956
163 + 31569793 = 31569956
193 + 31569763 = 31569956
577 + 31569379 = 31569956

Showing the first eight; more decompositions exist.
