Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004978, here are decompositions:

61 + 1004917 = 1004978
67 + 1004911 = 1004978
181 + 1004797 = 1004978
199 + 1004779 = 1004978
229 + 1004749 = 1004978
241 + 1004737 = 1004978
307 + 1004671 = 1004978
379 + 1004599 = 1004978

Showing the first eight; more decompositions exist.
