Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556292, here are decompositions:

13 + 31556279 = 31556292
43 + 31556249 = 31556292
149 + 31556143 = 31556292
151 + 31556141 = 31556292
179 + 31556113 = 31556292
193 + 31556099 = 31556292
211 + 31556081 = 31556292
281 + 31556011 = 31556292

Showing the first eight; more decompositions exist.
