Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465484, here are decompositions:

3 + 31465481 = 31465484
67 + 31465417 = 31465484
163 + 31465321 = 31465484
241 + 31465243 = 31465484
307 + 31465177 = 31465484
331 + 31465153 = 31465484
373 + 31465111 = 31465484
601 + 31464883 = 31465484

Showing the first eight; more decompositions exist.
