Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517172, here are decompositions:

3 + 517169 = 517172
43 + 517129 = 517172
181 + 516991 = 517172
193 + 516979 = 517172
199 + 516973 = 517172
223 + 516949 = 517172
241 + 516931 = 517172
379 + 516793 = 517172

Showing the first eight; more decompositions exist.
