Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458834, here are decompositions:

5 + 31458829 = 31458834
13 + 31458821 = 31458834
37 + 31458797 = 31458834
47 + 31458787 = 31458834
73 + 31458761 = 31458834
131 + 31458703 = 31458834
137 + 31458697 = 31458834
167 + 31458667 = 31458834

Showing the first eight; more decompositions exist.
