Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539934, here are decompositions:

3 + 31539931 = 31539934
71 + 31539863 = 31539934
113 + 31539821 = 31539934
197 + 31539737 = 31539934
227 + 31539707 = 31539934
263 + 31539671 = 31539934
347 + 31539587 = 31539934
467 + 31539467 = 31539934

Showing the first eight; more decompositions exist.
