Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589306, here are decompositions:

3 + 31589303 = 31589306
13 + 31589293 = 31589306
19 + 31589287 = 31589306
109 + 31589197 = 31589306
139 + 31589167 = 31589306
313 + 31588993 = 31589306
349 + 31588957 = 31589306
373 + 31588933 = 31589306

Showing the first eight; more decompositions exist.
