Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473724, here are decompositions:

17 + 31473707 = 31473724
131 + 31473593 = 31473724
311 + 31473413 = 31473724
461 + 31473263 = 31473724
521 + 31473203 = 31473724
563 + 31473161 = 31473724
617 + 31473107 = 31473724
641 + 31473083 = 31473724

Showing the first eight; more decompositions exist.
