Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461422, here are decompositions:

19 + 31461403 = 31461422
61 + 31461361 = 31461422
73 + 31461349 = 31461422
79 + 31461343 = 31461422
193 + 31461229 = 31461422
199 + 31461223 = 31461422
229 + 31461193 = 31461422
241 + 31461181 = 31461422

Showing the first eight; more decompositions exist.
