Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483448, here are decompositions:

19 + 31483429 = 31483448
79 + 31483369 = 31483448
97 + 31483351 = 31483448
211 + 31483237 = 31483448
331 + 31483117 = 31483448
379 + 31483069 = 31483448
397 + 31483051 = 31483448
457 + 31482991 = 31483448

Showing the first eight; more decompositions exist.
