Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534894, here are decompositions:

23 + 31534871 = 31534894
107 + 31534787 = 31534894
137 + 31534757 = 31534894
257 + 31534637 = 31534894
263 + 31534631 = 31534894
401 + 31534493 = 31534894
467 + 31534427 = 31534894
593 + 31534301 = 31534894

Showing the first eight; more decompositions exist.
