Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502778, here are decompositions:

7 + 502771 = 502778
61 + 502717 = 502778
79 + 502699 = 502778
109 + 502669 = 502778
127 + 502651 = 502778
181 + 502597 = 502778
229 + 502549 = 502778
271 + 502507 = 502778

Showing the first eight; more decompositions exist.
