Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609876, here are decompositions:

5 + 31609871 = 31609876
29 + 31609847 = 31609876
83 + 31609793 = 31609876
107 + 31609769 = 31609876
173 + 31609703 = 31609876
197 + 31609679 = 31609876
293 + 31609583 = 31609876
383 + 31609493 = 31609876

Showing the first eight; more decompositions exist.
