Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515354, here are decompositions:

3 + 515351 = 515354
31 + 515323 = 515354
43 + 515311 = 515354
61 + 515293 = 515354
127 + 515227 = 515354
163 + 515191 = 515354
181 + 515173 = 515354
211 + 515143 = 515354

Showing the first eight; more decompositions exist.
