Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582588, here are decompositions:

29 + 31582559 = 31582588
41 + 31582547 = 31582588
179 + 31582409 = 31582588
251 + 31582337 = 31582588
269 + 31582319 = 31582588
347 + 31582241 = 31582588
467 + 31582121 = 31582588
491 + 31582097 = 31582588

Showing the first eight; more decompositions exist.
