Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525582, here are decompositions:

29 + 31525553 = 31525582
83 + 31525499 = 31525582
239 + 31525343 = 31525582
251 + 31525331 = 31525582
293 + 31525289 = 31525582
353 + 31525229 = 31525582
419 + 31525163 = 31525582
461 + 31525121 = 31525582

Showing the first eight; more decompositions exist.
