Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544350, here are decompositions:

3 + 31544347 = 31544350
53 + 31544297 = 31544350
137 + 31544213 = 31544350
179 + 31544171 = 31544350
197 + 31544153 = 31544350
251 + 31544099 = 31544350
293 + 31544057 = 31544350
311 + 31544039 = 31544350

Showing the first eight; more decompositions exist.
