Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458926, here are decompositions:

3 + 31458923 = 31458926
13 + 31458913 = 31458926
19 + 31458907 = 31458926
97 + 31458829 = 31458926
127 + 31458799 = 31458926
139 + 31458787 = 31458926
223 + 31458703 = 31458926
229 + 31458697 = 31458926

Showing the first eight; more decompositions exist.
