Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568876, here are decompositions:

7 + 31568869 = 31568876
37 + 31568839 = 31568876
43 + 31568833 = 31568876
67 + 31568809 = 31568876
109 + 31568767 = 31568876
127 + 31568749 = 31568876
139 + 31568737 = 31568876
337 + 31568539 = 31568876

Showing the first eight; more decompositions exist.
