Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558964, here are decompositions:

7 + 31558957 = 31558964
37 + 31558927 = 31558964
67 + 31558897 = 31558964
193 + 31558771 = 31558964
223 + 31558741 = 31558964
271 + 31558693 = 31558964
331 + 31558633 = 31558964
337 + 31558627 = 31558964

Showing the first eight; more decompositions exist.
