Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515162, here are decompositions:

13 + 515149 = 515162
19 + 515143 = 515162
73 + 515089 = 515162
223 + 514939 = 515162
229 + 514933 = 515162
331 + 514831 = 515162
379 + 514783 = 515162
421 + 514741 = 515162

Showing the first eight; more decompositions exist.
