Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568952, here are decompositions:

13 + 31568939 = 31568952
31 + 31568921 = 31568952
43 + 31568909 = 31568952
73 + 31568879 = 31568952
83 + 31568869 = 31568952
101 + 31568851 = 31568952
109 + 31568843 = 31568952
113 + 31568839 = 31568952

Showing the first eight; more decompositions exist.
