Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559010, here are decompositions:

13 + 31558997 = 31559010
17 + 31558993 = 31559010
37 + 31558973 = 31559010
47 + 31558963 = 31559010
53 + 31558957 = 31559010
71 + 31558939 = 31559010
83 + 31558927 = 31559010
113 + 31558897 = 31559010

Showing the first eight; more decompositions exist.
