Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004840, here are decompositions:

43 + 1004797 = 1004840
61 + 1004779 = 1004840
79 + 1004761 = 1004840
97 + 1004743 = 1004840
103 + 1004737 = 1004840
163 + 1004677 = 1004840
181 + 1004659 = 1004840
241 + 1004599 = 1004840

Showing the first eight; more decompositions exist.
