Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582236, here are decompositions:

19 + 31582217 = 31582236
29 + 31582207 = 31582236
43 + 31582193 = 31582236
53 + 31582183 = 31582236
73 + 31582163 = 31582236
139 + 31582097 = 31582236
193 + 31582043 = 31582236
199 + 31582037 = 31582236

Showing the first eight; more decompositions exist.
