Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545564, here are decompositions:

157 + 31545407 = 31545564
163 + 31545401 = 31545564
173 + 31545391 = 31545564
191 + 31545373 = 31545564
233 + 31545331 = 31545564
241 + 31545323 = 31545564
277 + 31545287 = 31545564
331 + 31545233 = 31545564

Showing the first eight; more decompositions exist.
