Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609024, here are decompositions:

53 + 31608971 = 31609024
71 + 31608953 = 31609024
107 + 31608917 = 31609024
113 + 31608911 = 31609024
131 + 31608893 = 31609024
137 + 31608887 = 31609024
173 + 31608851 = 31609024
311 + 31608713 = 31609024

Showing the first eight; more decompositions exist.
