Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609244, here are decompositions:

13 + 31609231 = 31609244
31 + 31609213 = 31609244
127 + 31609117 = 31609244
151 + 31609093 = 31609244
157 + 31609087 = 31609244
211 + 31609033 = 31609244
307 + 31608937 = 31609244
421 + 31608823 = 31609244

Showing the first eight; more decompositions exist.
