Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582392, here are decompositions:

59 + 31582333 = 31582392
71 + 31582321 = 31582392
73 + 31582319 = 31582392
151 + 31582241 = 31582392
199 + 31582193 = 31582392
229 + 31582163 = 31582392
271 + 31582121 = 31582392
349 + 31582043 = 31582392

Showing the first eight; more decompositions exist.
