Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589348, here are decompositions:

19 + 31589329 = 31589348
31 + 31589317 = 31589348
61 + 31589287 = 31589348
97 + 31589251 = 31589348
151 + 31589197 = 31589348
181 + 31589167 = 31589348
211 + 31589137 = 31589348
229 + 31589119 = 31589348

Showing the first eight; more decompositions exist.
