Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467798, here are decompositions:

31 + 31467767 = 31467798
71 + 31467727 = 31467798
79 + 31467719 = 31467798
107 + 31467691 = 31467798
151 + 31467647 = 31467798
211 + 31467587 = 31467798
227 + 31467571 = 31467798
239 + 31467559 = 31467798

Showing the first eight; more decompositions exist.
