Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556202, here are decompositions:

53 + 31556149 = 31556202
59 + 31556143 = 31556202
61 + 31556141 = 31556202
89 + 31556113 = 31556202
103 + 31556099 = 31556202
191 + 31556011 = 31556202
211 + 31555991 = 31556202
233 + 31555969 = 31556202

Showing the first eight; more decompositions exist.
