Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463392, here are decompositions:

3 + 31463389 = 31463392
5 + 31463387 = 31463392
29 + 31463363 = 31463392
71 + 31463321 = 31463392
131 + 31463261 = 31463392
179 + 31463213 = 31463392
269 + 31463123 = 31463392
293 + 31463099 = 31463392

Showing the first eight; more decompositions exist.
