Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609026, here are decompositions:

67 + 31608959 = 31609026
73 + 31608953 = 31609026
89 + 31608937 = 31609026
109 + 31608917 = 31609026
139 + 31608887 = 31609026
173 + 31608853 = 31609026
233 + 31608793 = 31609026
269 + 31608757 = 31609026

Showing the first eight; more decompositions exist.
