Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516782, here are decompositions:

61 + 516721 = 516782
73 + 516709 = 516782
103 + 516679 = 516782
109 + 516673 = 516782
139 + 516643 = 516782
163 + 516619 = 516782
193 + 516589 = 516782
241 + 516541 = 516782

Showing the first eight; more decompositions exist.
