Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589184, here are decompositions:

17 + 31589167 = 31589184
47 + 31589137 = 31589184
97 + 31589087 = 31589184
127 + 31589057 = 31589184
157 + 31589027 = 31589184
167 + 31589017 = 31589184
173 + 31589011 = 31589184
191 + 31588993 = 31589184

Showing the first eight; more decompositions exist.
