Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582524, here are decompositions:

11 + 31582513 = 31582524
53 + 31582471 = 31582524
107 + 31582417 = 31582524
191 + 31582333 = 31582524
257 + 31582267 = 31582524
283 + 31582241 = 31582524
307 + 31582217 = 31582524
317 + 31582207 = 31582524

Showing the first eight; more decompositions exist.
