Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582344, here are decompositions:

7 + 31582337 = 31582344
11 + 31582333 = 31582344
23 + 31582321 = 31582344
103 + 31582241 = 31582344
127 + 31582217 = 31582344
137 + 31582207 = 31582344
151 + 31582193 = 31582344
173 + 31582171 = 31582344

Showing the first eight; more decompositions exist.
