Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500998, here are decompositions:

41 + 500957 = 500998
89 + 500909 = 500998
107 + 500891 = 500998
137 + 500861 = 500998
167 + 500831 = 500998
191 + 500807 = 500998
257 + 500741 = 500998
269 + 500729 = 500998

Showing the first eight; more decompositions exist.
