Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515100, here are decompositions:

11 + 515089 = 515100
13 + 515087 = 515100
59 + 515041 = 515100
151 + 514949 = 515100
167 + 514933 = 515100
197 + 514903 = 515100
211 + 514889 = 515100
227 + 514873 = 515100

Showing the first eight; more decompositions exist.
