Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539694, here are decompositions:

23 + 31539671 = 31539694
101 + 31539593 = 31539694
107 + 31539587 = 31539694
227 + 31539467 = 31539694
281 + 31539413 = 31539694
293 + 31539401 = 31539694
317 + 31539377 = 31539694
503 + 31539191 = 31539694

Showing the first eight; more decompositions exist.
