Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465068, here are decompositions:

7 + 31465061 = 31465068
29 + 31465039 = 31465068
101 + 31464967 = 31465068
127 + 31464941 = 31465068
241 + 31464827 = 31465068
281 + 31464787 = 31465068
311 + 31464757 = 31465068
337 + 31464731 = 31465068

Showing the first eight; more decompositions exist.
