Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465246, here are decompositions:

3 + 31465243 = 31465246
23 + 31465223 = 31465246
53 + 31465193 = 31465246
419 + 31464827 = 31465246
887 + 31464359 = 31465246
977 + 31464269 = 31465246
1013 + 31464233 = 31465246
1097 + 31464149 = 31465246

Showing the first eight; more decompositions exist.
