Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461494, here are decompositions:

7 + 31461487 = 31461494
13 + 31461481 = 31461494
37 + 31461457 = 31461494
67 + 31461427 = 31461494
151 + 31461343 = 31461494
193 + 31461301 = 31461494
241 + 31461253 = 31461494
271 + 31461223 = 31461494

Showing the first eight; more decompositions exist.
