Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556262, here are decompositions:

13 + 31556249 = 31556262
19 + 31556243 = 31556262
61 + 31556201 = 31556262
113 + 31556149 = 31556262
149 + 31556113 = 31556262
163 + 31556099 = 31556262
181 + 31556081 = 31556262
229 + 31556033 = 31556262

Showing the first eight; more decompositions exist.
