Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582184, here are decompositions:

13 + 31582171 = 31582184
157 + 31582027 = 31582184
163 + 31582021 = 31582184
181 + 31582003 = 31582184
211 + 31581973 = 31582184
223 + 31581961 = 31582184
307 + 31581877 = 31582184
367 + 31581817 = 31582184

Showing the first eight; more decompositions exist.
