Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516830, here are decompositions:

19 + 516811 = 516830
37 + 516793 = 516830
73 + 516757 = 516830
103 + 516727 = 516830
109 + 516721 = 516830
151 + 516679 = 516830
157 + 516673 = 516830
211 + 516619 = 516830

Showing the first eight; more decompositions exist.
