Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582412, here are decompositions:

3 + 31582409 = 31582412
13 + 31582399 = 31582412
79 + 31582333 = 31582412
163 + 31582249 = 31582412
229 + 31582183 = 31582412
241 + 31582171 = 31582412
409 + 31582003 = 31582412
439 + 31581973 = 31582412

Showing the first eight; more decompositions exist.
