Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550964, here are decompositions:

17 + 31550947 = 31550964
41 + 31550923 = 31550964
43 + 31550921 = 31550964
97 + 31550867 = 31550964
113 + 31550851 = 31550964
127 + 31550837 = 31550964
131 + 31550833 = 31550964
157 + 31550807 = 31550964

Showing the first eight; more decompositions exist.
