Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463460, here are decompositions:

31 + 31463429 = 31463460
53 + 31463407 = 31463460
71 + 31463389 = 31463460
73 + 31463387 = 31463460
97 + 31463363 = 31463460
107 + 31463353 = 31463460
131 + 31463329 = 31463460
139 + 31463321 = 31463460

Showing the first eight; more decompositions exist.
