Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539484, here are decompositions:

17 + 31539467 = 31539484
71 + 31539413 = 31539484
83 + 31539401 = 31539484
107 + 31539377 = 31539484
131 + 31539353 = 31539484
293 + 31539191 = 31539484
401 + 31539083 = 31539484
677 + 31538807 = 31539484

Showing the first eight; more decompositions exist.
