Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589682, here are decompositions:

23 + 31589659 = 31589682
71 + 31589611 = 31589682
199 + 31589483 = 31589682
281 + 31589401 = 31589682
349 + 31589333 = 31589682
353 + 31589329 = 31589682
379 + 31589303 = 31589682
389 + 31589293 = 31589682

Showing the first eight; more decompositions exist.
