Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518050, here are decompositions:

3 + 518047 = 518050
59 + 517991 = 518050
83 + 517967 = 518050
101 + 517949 = 518050
131 + 517919 = 518050
149 + 517901 = 518050
173 + 517877 = 518050
227 + 517823 = 518050

Showing the first eight; more decompositions exist.
