Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582366, here are decompositions:

29 + 31582337 = 31582366
47 + 31582319 = 31582366
149 + 31582217 = 31582366
173 + 31582193 = 31582366
269 + 31582097 = 31582366
317 + 31582049 = 31582366
383 + 31581983 = 31582366
419 + 31581947 = 31582366

Showing the first eight; more decompositions exist.
