Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515150, here are decompositions:

7 + 515143 = 515150
61 + 515089 = 515150
109 + 515041 = 515150
211 + 514939 = 515150
277 + 514873 = 515150
283 + 514867 = 515150
331 + 514819 = 515150
367 + 514783 = 515150

Showing the first eight; more decompositions exist.
