Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461356, here are decompositions:

7 + 31461349 = 31461356
13 + 31461343 = 31461356
103 + 31461253 = 31461356
127 + 31461229 = 31461356
163 + 31461193 = 31461356
193 + 31461163 = 31461356
229 + 31461127 = 31461356
307 + 31461049 = 31461356

Showing the first eight; more decompositions exist.
