Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049978, here are decompositions:

37 + 1049941 = 1049978
79 + 1049899 = 1049978
151 + 1049827 = 1049978
157 + 1049821 = 1049978
271 + 1049707 = 1049978
367 + 1049611 = 1049978
379 + 1049599 = 1049978
409 + 1049569 = 1049978

Showing the first eight; more decompositions exist.
