Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458824, here are decompositions:

3 + 31458821 = 31458824
37 + 31458787 = 31458824
127 + 31458697 = 31458824
157 + 31458667 = 31458824
181 + 31458643 = 31458824
193 + 31458631 = 31458824
223 + 31458601 = 31458824
283 + 31458541 = 31458824

Showing the first eight; more decompositions exist.
