Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588970, here are decompositions:

13 + 31588957 = 31588970
19 + 31588951 = 31588970
37 + 31588933 = 31588970
43 + 31588927 = 31588970
73 + 31588897 = 31588970
157 + 31588813 = 31588970
163 + 31588807 = 31588970
271 + 31588699 = 31588970

Showing the first eight; more decompositions exist.
