Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465998, here are decompositions:

19 + 31465979 = 31465998
107 + 31465891 = 31465998
149 + 31465849 = 31465998
167 + 31465831 = 31465998
197 + 31465801 = 31465998
241 + 31465757 = 31465998
251 + 31465747 = 31465998
257 + 31465741 = 31465998

Showing the first eight; more decompositions exist.
