Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515322, here are decompositions:

11 + 515311 = 515322
29 + 515293 = 515322
43 + 515279 = 515322
89 + 515233 = 515322
131 + 515191 = 515322
149 + 515173 = 515322
173 + 515149 = 515322
179 + 515143 = 515322

Showing the first eight; more decompositions exist.
