Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609296, here are decompositions:

7 + 31609289 = 31609296
29 + 31609267 = 31609296
67 + 31609229 = 31609296
73 + 31609223 = 31609296
83 + 31609213 = 31609296
107 + 31609189 = 31609296
179 + 31609117 = 31609296
263 + 31609033 = 31609296

Showing the first eight; more decompositions exist.
