Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582734, here are decompositions:

5 + 31582729 = 31582734
61 + 31582673 = 31582734
67 + 31582667 = 31582734
101 + 31582633 = 31582734
103 + 31582631 = 31582734
107 + 31582627 = 31582734
181 + 31582553 = 31582734
263 + 31582471 = 31582734

Showing the first eight; more decompositions exist.
