Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463400, here are decompositions:

11 + 31463389 = 31463400
13 + 31463387 = 31463400
37 + 31463363 = 31463400
47 + 31463353 = 31463400
71 + 31463329 = 31463400
79 + 31463321 = 31463400
83 + 31463317 = 31463400
131 + 31463269 = 31463400

Showing the first eight; more decompositions exist.
