Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556952, here are decompositions:

13 + 31556939 = 31556952
29 + 31556923 = 31556952
41 + 31556911 = 31556952
43 + 31556909 = 31556952
83 + 31556869 = 31556952
139 + 31556813 = 31556952
149 + 31556803 = 31556952
173 + 31556779 = 31556952

Showing the first eight; more decompositions exist.
