Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580344, here are decompositions:

17 + 31580327 = 31580344
23 + 31580321 = 31580344
71 + 31580273 = 31580344
113 + 31580231 = 31580344
137 + 31580207 = 31580344
167 + 31580177 = 31580344
233 + 31580111 = 31580344
251 + 31580093 = 31580344

Showing the first eight; more decompositions exist.
