Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582246, here are decompositions:

5 + 31582241 = 31582246
29 + 31582217 = 31582246
53 + 31582193 = 31582246
83 + 31582163 = 31582246
149 + 31582097 = 31582246
197 + 31582049 = 31582246
263 + 31581983 = 31582246
383 + 31581863 = 31582246

Showing the first eight; more decompositions exist.
