Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589156, here are decompositions:

19 + 31589137 = 31589156
37 + 31589119 = 31589156
139 + 31589017 = 31589156
163 + 31588993 = 31589156
199 + 31588957 = 31589156
223 + 31588933 = 31589156
229 + 31588927 = 31589156
349 + 31588807 = 31589156

Showing the first eight; more decompositions exist.
