Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589508, here are decompositions:

47 + 31589461 = 31589508
101 + 31589407 = 31589508
107 + 31589401 = 31589508
131 + 31589377 = 31589508
149 + 31589359 = 31589508
179 + 31589329 = 31589508
191 + 31589317 = 31589508
211 + 31589297 = 31589508

Showing the first eight; more decompositions exist.
