Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569032, here are decompositions:

163 + 31568869 = 31569032
181 + 31568851 = 31569032
193 + 31568839 = 31569032
199 + 31568833 = 31569032
223 + 31568809 = 31569032
283 + 31568749 = 31569032
331 + 31568701 = 31569032
421 + 31568611 = 31569032

Showing the first eight; more decompositions exist.
