Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465462, here are decompositions:

3 + 31465459 = 31465462
11 + 31465451 = 31465462
71 + 31465391 = 31465462
173 + 31465289 = 31465462
239 + 31465223 = 31465462
269 + 31465193 = 31465462
401 + 31465061 = 31465462
521 + 31464941 = 31465462

Showing the first eight; more decompositions exist.
