Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515418, here are decompositions:

17 + 515401 = 515418
37 + 515381 = 515418
41 + 515377 = 515418
47 + 515371 = 515418
61 + 515357 = 515418
67 + 515351 = 515418
107 + 515311 = 515418
139 + 515279 = 515418

Showing the first eight; more decompositions exist.
