Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043978, here are decompositions:

79 + 1043899 = 1043978
109 + 1043869 = 1043978
139 + 1043839 = 1043978
211 + 1043767 = 1043978
277 + 1043701 = 1043978
379 + 1043599 = 1043978
421 + 1043557 = 1043978
457 + 1043521 = 1043978

Showing the first eight; more decompositions exist.
