Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560888, here are decompositions:

17 + 31560871 = 31560888
19 + 31560869 = 31560888
41 + 31560847 = 31560888
89 + 31560799 = 31560888
97 + 31560791 = 31560888
131 + 31560757 = 31560888
137 + 31560751 = 31560888
157 + 31560731 = 31560888

Showing the first eight; more decompositions exist.
