Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458846, here are decompositions:

17 + 31458829 = 31458846
47 + 31458799 = 31458846
59 + 31458787 = 31458846
127 + 31458719 = 31458846
137 + 31458709 = 31458846
149 + 31458697 = 31458846
157 + 31458689 = 31458846
179 + 31458667 = 31458846

Showing the first eight; more decompositions exist.
