Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448984, here are decompositions:

163 + 31448821 = 31448984
181 + 31448803 = 31448984
271 + 31448713 = 31448984
277 + 31448707 = 31448984
337 + 31448647 = 31448984
397 + 31448587 = 31448984
433 + 31448551 = 31448984
571 + 31448413 = 31448984

Showing the first eight; more decompositions exist.
