Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492048, here are decompositions:

17 + 31492031 = 31492048
59 + 31491989 = 31492048
89 + 31491959 = 31492048
131 + 31491917 = 31492048
167 + 31491881 = 31492048
257 + 31491791 = 31492048
311 + 31491737 = 31492048
389 + 31491659 = 31492048

Showing the first eight; more decompositions exist.
