Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609102, here are decompositions:

11 + 31609091 = 31609102
23 + 31609079 = 31609102
53 + 31609049 = 31609102
71 + 31609031 = 31609102
131 + 31608971 = 31609102
149 + 31608953 = 31609102
191 + 31608911 = 31609102
251 + 31608851 = 31609102

Showing the first eight; more decompositions exist.
