Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006778, here are decompositions:

67 + 1006711 = 1006778
127 + 1006651 = 1006778
271 + 1006507 = 1006778
307 + 1006471 = 1006778
337 + 1006441 = 1006778
439 + 1006339 = 1006778
499 + 1006279 = 1006778
541 + 1006237 = 1006778

Showing the first eight; more decompositions exist.
