Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606074, here are decompositions:

7 + 31606067 = 31606074
13 + 31606061 = 31606074
23 + 31606051 = 31606074
103 + 31605971 = 31606074
197 + 31605877 = 31606074
251 + 31605823 = 31606074
263 + 31605811 = 31606074
271 + 31605803 = 31606074

Showing the first eight; more decompositions exist.
