Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582600, here are decompositions:

11 + 31582589 = 31582600
41 + 31582559 = 31582600
47 + 31582553 = 31582600
53 + 31582547 = 31582600
191 + 31582409 = 31582600
197 + 31582403 = 31582600
263 + 31582337 = 31582600
281 + 31582319 = 31582600

Showing the first eight; more decompositions exist.
