Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582244, here are decompositions:

3 + 31582241 = 31582244
37 + 31582207 = 31582244
61 + 31582183 = 31582244
73 + 31582171 = 31582244
151 + 31582093 = 31582244
223 + 31582021 = 31582244
241 + 31582003 = 31582244
271 + 31581973 = 31582244

Showing the first eight; more decompositions exist.
