Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589504, here are decompositions:

31 + 31589473 = 31589504
43 + 31589461 = 31589504
97 + 31589407 = 31589504
103 + 31589401 = 31589504
127 + 31589377 = 31589504
151 + 31589353 = 31589504
211 + 31589293 = 31589504
307 + 31589197 = 31589504

Showing the first eight; more decompositions exist.
