Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513724, here are decompositions:

5 + 513719 = 513724
41 + 513683 = 513724
83 + 513641 = 513724
131 + 513593 = 513724
191 + 513533 = 513724
251 + 513473 = 513724
293 + 513431 = 513724
317 + 513407 = 513724

Showing the first eight; more decompositions exist.
