Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539994, here are decompositions:

23 + 31539971 = 31539994
131 + 31539863 = 31539994
137 + 31539857 = 31539994
173 + 31539821 = 31539994
257 + 31539737 = 31539994
281 + 31539713 = 31539994
401 + 31539593 = 31539994
593 + 31539401 = 31539994

Showing the first eight; more decompositions exist.
