Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582676, here are decompositions:

3 + 31582673 = 31582676
43 + 31582633 = 31582676
67 + 31582609 = 31582676
163 + 31582513 = 31582676
277 + 31582399 = 31582676
409 + 31582267 = 31582676
673 + 31582003 = 31582676
787 + 31581889 = 31582676

Showing the first eight; more decompositions exist.
