Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452448, here are decompositions:

29 + 31452419 = 31452448
47 + 31452401 = 31452448
107 + 31452341 = 31452448
239 + 31452209 = 31452448
311 + 31452137 = 31452448
317 + 31452131 = 31452448
359 + 31452089 = 31452448
449 + 31451999 = 31452448

Showing the first eight; more decompositions exist.
