Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568796, here are decompositions:

29 + 31568767 = 31568796
47 + 31568749 = 31568796
53 + 31568743 = 31568796
59 + 31568737 = 31568796
73 + 31568723 = 31568796
139 + 31568657 = 31568796
167 + 31568629 = 31568796
257 + 31568539 = 31568796

Showing the first eight; more decompositions exist.
