Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582436, here are decompositions:

19 + 31582417 = 31582436
37 + 31582399 = 31582436
103 + 31582333 = 31582436
229 + 31582207 = 31582436
409 + 31582027 = 31582436
433 + 31582003 = 31582436
439 + 31581997 = 31582436
463 + 31581973 = 31582436

Showing the first eight; more decompositions exist.
