Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458876, here are decompositions:

13 + 31458863 = 31458876
47 + 31458829 = 31458876
79 + 31458797 = 31458876
89 + 31458787 = 31458876
157 + 31458719 = 31458876
167 + 31458709 = 31458876
173 + 31458703 = 31458876
179 + 31458697 = 31458876

Showing the first eight; more decompositions exist.
