Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582744, here are decompositions:

5 + 31582739 = 31582744
71 + 31582673 = 31582744
113 + 31582631 = 31582744
131 + 31582613 = 31582744
191 + 31582553 = 31582744
197 + 31582547 = 31582744
503 + 31582241 = 31582744
647 + 31582097 = 31582744

Showing the first eight; more decompositions exist.
