Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550934, here are decompositions:

11 + 31550923 = 31550934
13 + 31550921 = 31550934
67 + 31550867 = 31550934
83 + 31550851 = 31550934
97 + 31550837 = 31550934
101 + 31550833 = 31550934
127 + 31550807 = 31550934
131 + 31550803 = 31550934

Showing the first eight; more decompositions exist.
