Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039978, here are decompositions:

29 + 1039949 = 1039978
47 + 1039931 = 1039978
179 + 1039799 = 1039978
311 + 1039667 = 1039978
347 + 1039631 = 1039978
461 + 1039517 = 1039978
509 + 1039469 = 1039978
557 + 1039421 = 1039978

Showing the first eight; more decompositions exist.
