Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589408, here are decompositions:

7 + 31589401 = 31589408
31 + 31589377 = 31589408
79 + 31589329 = 31589408
157 + 31589251 = 31589408
211 + 31589197 = 31589408
241 + 31589167 = 31589408
271 + 31589137 = 31589408
397 + 31589011 = 31589408

Showing the first eight; more decompositions exist.
