Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609132, here are decompositions:

41 + 31609091 = 31609132
53 + 31609079 = 31609132
83 + 31609049 = 31609132
101 + 31609031 = 31609132
173 + 31608959 = 31609132
179 + 31608953 = 31609132
239 + 31608893 = 31609132
281 + 31608851 = 31609132

Showing the first eight; more decompositions exist.
