Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556182, here are decompositions:

41 + 31556141 = 31556182
83 + 31556099 = 31556182
101 + 31556081 = 31556182
149 + 31556033 = 31556182
191 + 31555991 = 31556182
233 + 31555949 = 31556182
311 + 31555871 = 31556182
401 + 31555781 = 31556182

Showing the first eight; more decompositions exist.
