Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568062, here are decompositions:

3 + 31568059 = 31568062
41 + 31568021 = 31568062
101 + 31567961 = 31568062
131 + 31567931 = 31568062
179 + 31567883 = 31568062
293 + 31567769 = 31568062
353 + 31567709 = 31568062
389 + 31567673 = 31568062

Showing the first eight; more decompositions exist.
