Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492448, here are decompositions:

19 + 31492429 = 31492448
79 + 31492369 = 31492448
367 + 31492081 = 31492448
397 + 31492051 = 31492448
607 + 31491841 = 31492448
661 + 31491787 = 31492448
751 + 31491697 = 31492448
769 + 31491679 = 31492448

Showing the first eight; more decompositions exist.
