Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589468, here are decompositions:

7 + 31589461 = 31589468
61 + 31589407 = 31589468
67 + 31589401 = 31589468
109 + 31589359 = 31589468
139 + 31589329 = 31589468
151 + 31589317 = 31589468
181 + 31589287 = 31589468
271 + 31589197 = 31589468

Showing the first eight; more decompositions exist.
