Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606976, here are decompositions:

3 + 31606973 = 31606976
13 + 31606963 = 31606976
19 + 31606957 = 31606976
73 + 31606903 = 31606976
97 + 31606879 = 31606976
223 + 31606753 = 31606976
397 + 31606579 = 31606976
433 + 31606543 = 31606976

Showing the first eight; more decompositions exist.
