Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464494, here are decompositions:

13 + 31464481 = 31464494
31 + 31464463 = 31464494
43 + 31464451 = 31464494
67 + 31464427 = 31464494
73 + 31464421 = 31464494
97 + 31464397 = 31464494
223 + 31464271 = 31464494
307 + 31464187 = 31464494

Showing the first eight; more decompositions exist.
