Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606794, here are decompositions:

41 + 31606753 = 31606794
53 + 31606741 = 31606794
67 + 31606727 = 31606794
83 + 31606711 = 31606794
97 + 31606697 = 31606794
103 + 31606691 = 31606794
113 + 31606681 = 31606794
127 + 31606667 = 31606794

Showing the first eight; more decompositions exist.
