Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465230, here are decompositions:

7 + 31465223 = 31465230
37 + 31465193 = 31465230
47 + 31465183 = 31465230
53 + 31465177 = 31465230
101 + 31465129 = 31465230
107 + 31465123 = 31465230
131 + 31465099 = 31465230
191 + 31465039 = 31465230

Showing the first eight; more decompositions exist.
