Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582498, here are decompositions:

89 + 31582409 = 31582498
179 + 31582319 = 31582498
257 + 31582241 = 31582498
281 + 31582217 = 31582498
401 + 31582097 = 31582498
449 + 31582049 = 31582498
461 + 31582037 = 31582498
587 + 31581911 = 31582498

Showing the first eight; more decompositions exist.
