Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582422, here are decompositions:

5 + 31582417 = 31582422
13 + 31582409 = 31582422
19 + 31582403 = 31582422
23 + 31582399 = 31582422
89 + 31582333 = 31582422
101 + 31582321 = 31582422
103 + 31582319 = 31582422
173 + 31582249 = 31582422

Showing the first eight; more decompositions exist.
