Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609294, here are decompositions:

5 + 31609289 = 31609294
71 + 31609223 = 31609294
263 + 31609031 = 31609294
383 + 31608911 = 31609294
401 + 31608893 = 31609294
443 + 31608851 = 31609294
557 + 31608737 = 31609294
797 + 31608497 = 31609294

Showing the first eight; more decompositions exist.
