Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582482, here are decompositions:

11 + 31582471 = 31582482
73 + 31582409 = 31582482
79 + 31582403 = 31582482
83 + 31582399 = 31582482
149 + 31582333 = 31582482
163 + 31582319 = 31582482
233 + 31582249 = 31582482
241 + 31582241 = 31582482

Showing the first eight; more decompositions exist.
