Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468494, here are decompositions:

23 + 31468471 = 31468494
41 + 31468453 = 31468494
47 + 31468447 = 31468494
97 + 31468397 = 31468494
103 + 31468391 = 31468494
157 + 31468337 = 31468494
163 + 31468331 = 31468494
223 + 31468271 = 31468494

Showing the first eight; more decompositions exist.
