Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582736, here are decompositions:

7 + 31582729 = 31582736
103 + 31582633 = 31582736
109 + 31582627 = 31582736
127 + 31582609 = 31582736
223 + 31582513 = 31582736
337 + 31582399 = 31582736
487 + 31582249 = 31582736
643 + 31582093 = 31582736

Showing the first eight; more decompositions exist.
