Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463884, here are decompositions:

5 + 31463879 = 31463884
41 + 31463843 = 31463884
167 + 31463717 = 31463884
293 + 31463591 = 31463884
401 + 31463483 = 31463884
521 + 31463363 = 31463884
563 + 31463321 = 31463884
761 + 31463123 = 31463884

Showing the first eight; more decompositions exist.
