Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515370, here are decompositions:

13 + 515357 = 515370
19 + 515351 = 515370
47 + 515323 = 515370
59 + 515311 = 515370
137 + 515233 = 515370
139 + 515231 = 515370
179 + 515191 = 515370
197 + 515173 = 515370

Showing the first eight; more decompositions exist.
