Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556274, here are decompositions:

31 + 31556243 = 31556274
73 + 31556201 = 31556274
131 + 31556143 = 31556274
193 + 31556081 = 31556274
241 + 31556033 = 31556274
263 + 31556011 = 31556274
283 + 31555991 = 31556274
293 + 31555981 = 31556274

Showing the first eight; more decompositions exist.
