Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556052, here are decompositions:

19 + 31556033 = 31556052
41 + 31556011 = 31556052
53 + 31555999 = 31556052
61 + 31555991 = 31556052
71 + 31555981 = 31556052
83 + 31555969 = 31556052
103 + 31555949 = 31556052
113 + 31555939 = 31556052

Showing the first eight; more decompositions exist.
