Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556334, here are decompositions:

11 + 31556323 = 31556334
31 + 31556303 = 31556334
41 + 31556293 = 31556334
191 + 31556143 = 31556334
193 + 31556141 = 31556334
353 + 31555981 = 31556334
367 + 31555967 = 31556334
401 + 31555933 = 31556334

Showing the first eight; more decompositions exist.
