Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582338, here are decompositions:

5 + 31582333 = 31582338
17 + 31582321 = 31582338
19 + 31582319 = 31582338
71 + 31582267 = 31582338
89 + 31582249 = 31582338
97 + 31582241 = 31582338
131 + 31582207 = 31582338
167 + 31582171 = 31582338

Showing the first eight; more decompositions exist.
