Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556050, here are decompositions:

17 + 31556033 = 31556050
59 + 31555991 = 31556050
83 + 31555967 = 31556050
101 + 31555949 = 31556050
173 + 31555877 = 31556050
179 + 31555871 = 31556050
269 + 31555781 = 31556050
311 + 31555739 = 31556050

Showing the first eight; more decompositions exist.
