Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468078, here are decompositions:

11 + 31468067 = 31468078
167 + 31467911 = 31468078
179 + 31467899 = 31468078
269 + 31467809 = 31468078
311 + 31467767 = 31468078
359 + 31467719 = 31468078
401 + 31467677 = 31468078
431 + 31467647 = 31468078

Showing the first eight; more decompositions exist.
