Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609204, here are decompositions:

113 + 31609091 = 31609204
173 + 31609031 = 31609204
233 + 31608971 = 31609204
251 + 31608953 = 31609204
293 + 31608911 = 31609204
311 + 31608893 = 31609204
317 + 31608887 = 31609204
353 + 31608851 = 31609204

Showing the first eight; more decompositions exist.
