Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589592, here are decompositions:

31 + 31589561 = 31589592
53 + 31589539 = 31589592
79 + 31589513 = 31589592
109 + 31589483 = 31589592
131 + 31589461 = 31589592
191 + 31589401 = 31589592
233 + 31589359 = 31589592
239 + 31589353 = 31589592

Showing the first eight; more decompositions exist.
