Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606926, here are decompositions:

7 + 31606919 = 31606926
23 + 31606903 = 31606926
47 + 31606879 = 31606926
79 + 31606847 = 31606926
97 + 31606829 = 31606926
173 + 31606753 = 31606926
199 + 31606727 = 31606926
223 + 31606703 = 31606926

Showing the first eight; more decompositions exist.
