Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609068, here are decompositions:

19 + 31609049 = 31609068
37 + 31609031 = 31609068
97 + 31608971 = 31609068
109 + 31608959 = 31609068
131 + 31608937 = 31609068
151 + 31608917 = 31609068
157 + 31608911 = 31609068
181 + 31608887 = 31609068

Showing the first eight; more decompositions exist.
