Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556348, here are decompositions:

7 + 31556341 = 31556348
199 + 31556149 = 31556348
337 + 31556011 = 31556348
349 + 31555999 = 31556348
367 + 31555981 = 31556348
379 + 31555969 = 31556348
409 + 31555939 = 31556348
457 + 31555891 = 31556348

Showing the first eight; more decompositions exist.
