Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589368, here are decompositions:

29 + 31589339 = 31589368
47 + 31589321 = 31589368
71 + 31589297 = 31589368
269 + 31589099 = 31589368
281 + 31589087 = 31589368
311 + 31589057 = 31589368
389 + 31588979 = 31589368
521 + 31588847 = 31589368

Showing the first eight; more decompositions exist.
