Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513548, here are decompositions:

19 + 513529 = 513548
37 + 513511 = 513548
67 + 513481 = 513548
109 + 513439 = 513548
151 + 513397 = 513548
181 + 513367 = 513548
229 + 513319 = 513548
241 + 513307 = 513548

Showing the first eight; more decompositions exist.
