Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461410, here are decompositions:

7 + 31461403 = 31461410
61 + 31461349 = 31461410
67 + 31461343 = 31461410
109 + 31461301 = 31461410
157 + 31461253 = 31461410
181 + 31461229 = 31461410
229 + 31461181 = 31461410
283 + 31461127 = 31461410

Showing the first eight; more decompositions exist.
