Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556048, here are decompositions:

37 + 31556011 = 31556048
67 + 31555981 = 31556048
79 + 31555969 = 31556048
109 + 31555939 = 31556048
127 + 31555921 = 31556048
157 + 31555891 = 31556048
331 + 31555717 = 31556048
397 + 31555651 = 31556048

Showing the first eight; more decompositions exist.
