Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582606, here are decompositions:

5 + 31582601 = 31582606
17 + 31582589 = 31582606
47 + 31582559 = 31582606
53 + 31582553 = 31582606
59 + 31582547 = 31582606
197 + 31582409 = 31582606
269 + 31582337 = 31582606
389 + 31582217 = 31582606

Showing the first eight; more decompositions exist.
