Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499026, here are decompositions:

3 + 31499023 = 31499026
5 + 31499021 = 31499026
23 + 31499003 = 31499026
59 + 31498967 = 31499026
113 + 31498913 = 31499026
173 + 31498853 = 31499026
179 + 31498847 = 31499026
197 + 31498829 = 31499026

Showing the first eight; more decompositions exist.
