Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500816, here are decompositions:

7 + 500809 = 500816
97 + 500719 = 500816
103 + 500713 = 500816
139 + 500677 = 500816
229 + 500587 = 500816
307 + 500509 = 500816
373 + 500443 = 500816
499 + 500317 = 500816

Showing the first eight; more decompositions exist.
