Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582548, here are decompositions:

17 + 31582531 = 31582548
59 + 31582489 = 31582548
131 + 31582417 = 31582548
139 + 31582409 = 31582548
149 + 31582399 = 31582548
211 + 31582337 = 31582548
227 + 31582321 = 31582548
229 + 31582319 = 31582548

Showing the first eight; more decompositions exist.
