Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589496, here are decompositions:

13 + 31589483 = 31589496
23 + 31589473 = 31589496
73 + 31589423 = 31589496
89 + 31589407 = 31589496
137 + 31589359 = 31589496
157 + 31589339 = 31589496
163 + 31589333 = 31589496
167 + 31589329 = 31589496

Showing the first eight; more decompositions exist.
