Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515020, here are decompositions:

53 + 514967 = 515020
71 + 514949 = 515020
131 + 514889 = 515020
167 + 514853 = 515020
173 + 514847 = 515020
179 + 514841 = 515020
197 + 514823 = 515020
227 + 514793 = 515020

Showing the first eight; more decompositions exist.
