Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589148, here are decompositions:

11 + 31589137 = 31589148
29 + 31589119 = 31589148
61 + 31589087 = 31589148
79 + 31589069 = 31589148
131 + 31589017 = 31589148
137 + 31589011 = 31589148
191 + 31588957 = 31589148
197 + 31588951 = 31589148

Showing the first eight; more decompositions exist.
