Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606344, here are decompositions:

5 + 31606339 = 31606344
13 + 31606331 = 31606344
31 + 31606313 = 31606344
47 + 31606297 = 31606344
61 + 31606283 = 31606344
67 + 31606277 = 31606344
83 + 31606261 = 31606344
157 + 31606187 = 31606344

Showing the first eight; more decompositions exist.
