Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582414, here are decompositions:

5 + 31582409 = 31582414
11 + 31582403 = 31582414
173 + 31582241 = 31582414
197 + 31582217 = 31582414
251 + 31582163 = 31582414
293 + 31582121 = 31582414
317 + 31582097 = 31582414
431 + 31581983 = 31582414

Showing the first eight; more decompositions exist.
