Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568924, here are decompositions:

3 + 31568921 = 31568924
7 + 31568917 = 31568924
73 + 31568851 = 31568924
97 + 31568827 = 31568924
157 + 31568767 = 31568924
181 + 31568743 = 31568924
223 + 31568701 = 31568924
313 + 31568611 = 31568924

Showing the first eight; more decompositions exist.
