Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515046, here are decompositions:

5 + 515041 = 515046
79 + 514967 = 515046
97 + 514949 = 515046
107 + 514939 = 515046
113 + 514933 = 515046
157 + 514889 = 515046
173 + 514873 = 515046
179 + 514867 = 515046

Showing the first eight; more decompositions exist.
