Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463406, here are decompositions:

17 + 31463389 = 31463406
19 + 31463387 = 31463406
43 + 31463363 = 31463406
53 + 31463353 = 31463406
89 + 31463317 = 31463406
137 + 31463269 = 31463406
157 + 31463249 = 31463406
179 + 31463227 = 31463406

Showing the first eight; more decompositions exist.
