Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463584, here are decompositions:

101 + 31463483 = 31463584
107 + 31463477 = 31463584
197 + 31463387 = 31463584
263 + 31463321 = 31463584
461 + 31463123 = 31463584
521 + 31463063 = 31463584
653 + 31462931 = 31463584
683 + 31462901 = 31463584

Showing the first eight; more decompositions exist.
