Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465302, here are decompositions:

13 + 31465289 = 31465302
59 + 31465243 = 31465302
79 + 31465223 = 31465302
109 + 31465193 = 31465302
149 + 31465153 = 31465302
173 + 31465129 = 31465302
179 + 31465123 = 31465302
191 + 31465111 = 31465302

Showing the first eight; more decompositions exist.
