Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582342, here are decompositions:

5 + 31582337 = 31582342
23 + 31582319 = 31582342
101 + 31582241 = 31582342
149 + 31582193 = 31582342
179 + 31582163 = 31582342
293 + 31582049 = 31582342
359 + 31581983 = 31582342
431 + 31581911 = 31582342

Showing the first eight; more decompositions exist.
