Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582444, here are decompositions:

41 + 31582403 = 31582444
107 + 31582337 = 31582444
227 + 31582217 = 31582444
251 + 31582193 = 31582444
281 + 31582163 = 31582444
347 + 31582097 = 31582444
401 + 31582043 = 31582444
461 + 31581983 = 31582444

Showing the first eight; more decompositions exist.
