Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556254, here are decompositions:

5 + 31556249 = 31556254
11 + 31556243 = 31556254
53 + 31556201 = 31556254
113 + 31556141 = 31556254
173 + 31556081 = 31556254
263 + 31555991 = 31556254
347 + 31555907 = 31556254
383 + 31555871 = 31556254

Showing the first eight; more decompositions exist.
