Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019978, here are decompositions:

7 + 1019971 = 1019978
79 + 1019899 = 1019978
139 + 1019839 = 1019978
151 + 1019827 = 1019978
277 + 1019701 = 1019978
331 + 1019647 = 1019978
499 + 1019479 = 1019978
601 + 1019377 = 1019978

Showing the first eight; more decompositions exist.
