Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515232, here are decompositions:

5 + 515227 = 515232
41 + 515191 = 515232
59 + 515173 = 515232
79 + 515153 = 515232
83 + 515149 = 515232
89 + 515143 = 515232
191 + 515041 = 515232
283 + 514949 = 515232

Showing the first eight; more decompositions exist.
