Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465448, here are decompositions:

31 + 31465417 = 31465448
127 + 31465321 = 31465448
139 + 31465309 = 31465448
271 + 31465177 = 31465448
337 + 31465111 = 31465448
349 + 31465099 = 31465448
379 + 31465069 = 31465448
409 + 31465039 = 31465448

Showing the first eight; more decompositions exist.
