Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582724, here are decompositions:

97 + 31582627 = 31582724
193 + 31582531 = 31582724
211 + 31582513 = 31582724
307 + 31582417 = 31582724
457 + 31582267 = 31582724
541 + 31582183 = 31582724
631 + 31582093 = 31582724
727 + 31581997 = 31582724

Showing the first eight; more decompositions exist.
