Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589704, here are decompositions:

11 + 31589693 = 31589704
71 + 31589633 = 31589704
137 + 31589567 = 31589704
191 + 31589513 = 31589704
281 + 31589423 = 31589704
383 + 31589321 = 31589704
401 + 31589303 = 31589704
521 + 31589183 = 31589704

Showing the first eight; more decompositions exist.
