Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589160, here are decompositions:

23 + 31589137 = 31589160
41 + 31589119 = 31589160
61 + 31589099 = 31589160
73 + 31589087 = 31589160
103 + 31589057 = 31589160
149 + 31589011 = 31589160
167 + 31588993 = 31589160
181 + 31588979 = 31589160

Showing the first eight; more decompositions exist.
