Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582536, here are decompositions:

5 + 31582531 = 31582536
23 + 31582513 = 31582536
47 + 31582489 = 31582536
127 + 31582409 = 31582536
137 + 31582399 = 31582536
199 + 31582337 = 31582536
269 + 31582267 = 31582536
353 + 31582183 = 31582536

Showing the first eight; more decompositions exist.
