Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582582, here are decompositions:

23 + 31582559 = 31582582
29 + 31582553 = 31582582
173 + 31582409 = 31582582
179 + 31582403 = 31582582
263 + 31582319 = 31582582
389 + 31582193 = 31582582
419 + 31582163 = 31582582
461 + 31582121 = 31582582

Showing the first eight; more decompositions exist.
