Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609352, here are decompositions:

13 + 31609339 = 31609352
139 + 31609213 = 31609352
163 + 31609189 = 31609352
241 + 31609111 = 31609352
499 + 31608853 = 31609352
631 + 31608721 = 31609352
823 + 31608529 = 31609352
1033 + 31608319 = 31609352

Showing the first eight; more decompositions exist.
