Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556184, here are decompositions:

41 + 31556143 = 31556184
43 + 31556141 = 31556184
71 + 31556113 = 31556184
103 + 31556081 = 31556184
151 + 31556033 = 31556184
173 + 31556011 = 31556184
193 + 31555991 = 31556184
227 + 31555957 = 31556184

Showing the first eight; more decompositions exist.
