Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582452, here are decompositions:

43 + 31582409 = 31582452
53 + 31582399 = 31582452
131 + 31582321 = 31582452
211 + 31582241 = 31582452
269 + 31582183 = 31582452
281 + 31582171 = 31582452
331 + 31582121 = 31582452
359 + 31582093 = 31582452

Showing the first eight; more decompositions exist.
