Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589644, here are decompositions:

11 + 31589633 = 31589644
83 + 31589561 = 31589644
131 + 31589513 = 31589644
311 + 31589333 = 31589644
347 + 31589297 = 31589644
353 + 31589291 = 31589644
461 + 31589183 = 31589644
557 + 31589087 = 31589644

Showing the first eight; more decompositions exist.
