Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465804, here are decompositions:

3 + 31465801 = 31465804
23 + 31465781 = 31465804
47 + 31465757 = 31465804
107 + 31465697 = 31465804
131 + 31465673 = 31465804
173 + 31465631 = 31465804
233 + 31465571 = 31465804
257 + 31465547 = 31465804

Showing the first eight; more decompositions exist.
