Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513428, here are decompositions:

31 + 513397 = 513428
61 + 513367 = 513428
109 + 513319 = 513428
151 + 513277 = 513428
271 + 513157 = 513428
397 + 513031 = 513428
439 + 512989 = 513428
499 + 512929 = 513428

Showing the first eight; more decompositions exist.
