Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582506, here are decompositions:

17 + 31582489 = 31582506
89 + 31582417 = 31582506
97 + 31582409 = 31582506
103 + 31582403 = 31582506
107 + 31582399 = 31582506
173 + 31582333 = 31582506
239 + 31582267 = 31582506
257 + 31582249 = 31582506

Showing the first eight; more decompositions exist.
