Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556582, here are decompositions:

103 + 31556479 = 31556582
193 + 31556389 = 31556582
229 + 31556353 = 31556582
241 + 31556341 = 31556582
433 + 31556149 = 31556582
439 + 31556143 = 31556582
571 + 31556011 = 31556582
601 + 31555981 = 31556582

Showing the first eight; more decompositions exist.
