Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499022, here are decompositions:

19 + 31499003 = 31499022
29 + 31498993 = 31499022
31 + 31498991 = 31499022
59 + 31498963 = 31499022
73 + 31498949 = 31499022
109 + 31498913 = 31499022
173 + 31498849 = 31499022
193 + 31498829 = 31499022

Showing the first eight; more decompositions exist.
