Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515124, here are decompositions:

13 + 515111 = 515124
37 + 515087 = 515124
83 + 515041 = 515124
157 + 514967 = 515124
191 + 514933 = 515124
251 + 514873 = 515124
257 + 514867 = 515124
271 + 514853 = 515124

Showing the first eight; more decompositions exist.
