Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608076, here are decompositions:

29 + 31608047 = 31608076
47 + 31608029 = 31608076
107 + 31607969 = 31608076
167 + 31607909 = 31608076
173 + 31607903 = 31608076
179 + 31607897 = 31608076
293 + 31607783 = 31608076
359 + 31607717 = 31608076

Showing the first eight; more decompositions exist.
