Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467694, here are decompositions:

3 + 31467691 = 31467694
17 + 31467677 = 31467694
47 + 31467647 = 31467694
101 + 31467593 = 31467694
107 + 31467587 = 31467694
191 + 31467503 = 31467694
197 + 31467497 = 31467694
227 + 31467467 = 31467694

Showing the first eight; more decompositions exist.
