Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463544, here are decompositions:

11 + 31463533 = 31463544
17 + 31463527 = 31463544
37 + 31463507 = 31463544
61 + 31463483 = 31463544
67 + 31463477 = 31463544
137 + 31463407 = 31463544
157 + 31463387 = 31463544
181 + 31463363 = 31463544

Showing the first eight; more decompositions exist.
