Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446984, here are decompositions:

11 + 31446973 = 31446984
31 + 31446953 = 31446984
47 + 31446937 = 31446984
67 + 31446917 = 31446984
113 + 31446871 = 31446984
131 + 31446853 = 31446984
137 + 31446847 = 31446984
223 + 31446761 = 31446984

Showing the first eight; more decompositions exist.
