Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558704, here are decompositions:

11 + 31558693 = 31558704
31 + 31558673 = 31558704
41 + 31558663 = 31558704
71 + 31558633 = 31558704
97 + 31558607 = 31558704
137 + 31558567 = 31558704
241 + 31558463 = 31558704
251 + 31558453 = 31558704

Showing the first eight; more decompositions exist.
