Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609362, here are decompositions:

23 + 31609339 = 31609362
73 + 31609289 = 31609362
131 + 31609231 = 31609362
139 + 31609223 = 31609362
149 + 31609213 = 31609362
173 + 31609189 = 31609362
251 + 31609111 = 31609362
269 + 31609093 = 31609362

Showing the first eight; more decompositions exist.
