Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499778, here are decompositions:

31 + 499747 = 499778
61 + 499717 = 499778
67 + 499711 = 499778
109 + 499669 = 499778
157 + 499621 = 499778
229 + 499549 = 499778
271 + 499507 = 499778
457 + 499321 = 499778

Showing the first eight; more decompositions exist.
