Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515226, here are decompositions:

53 + 515173 = 515226
73 + 515153 = 515226
83 + 515143 = 515226
137 + 515089 = 515226
139 + 515087 = 515226
277 + 514949 = 515226
293 + 514933 = 515226
337 + 514889 = 515226

Showing the first eight; more decompositions exist.
