Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463376, here are decompositions:

13 + 31463363 = 31463376
23 + 31463353 = 31463376
47 + 31463329 = 31463376
59 + 31463317 = 31463376
107 + 31463269 = 31463376
127 + 31463249 = 31463376
149 + 31463227 = 31463376
163 + 31463213 = 31463376

Showing the first eight; more decompositions exist.
