Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609392, here are decompositions:

11 + 31609381 = 31609392
53 + 31609339 = 31609392
103 + 31609289 = 31609392
163 + 31609229 = 31609392
179 + 31609213 = 31609392
281 + 31609111 = 31609392
313 + 31609079 = 31609392
359 + 31609033 = 31609392

Showing the first eight; more decompositions exist.
