Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589256, here are decompositions:

5 + 31589251 = 31589256
59 + 31589197 = 31589256
73 + 31589183 = 31589256
89 + 31589167 = 31589256
137 + 31589119 = 31589256
157 + 31589099 = 31589256
199 + 31589057 = 31589256
229 + 31589027 = 31589256

Showing the first eight; more decompositions exist.
