Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582426, here are decompositions:

17 + 31582409 = 31582426
23 + 31582403 = 31582426
89 + 31582337 = 31582426
107 + 31582319 = 31582426
233 + 31582193 = 31582426
263 + 31582163 = 31582426
383 + 31582043 = 31582426
389 + 31582037 = 31582426

Showing the first eight; more decompositions exist.
