Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048840, here are decompositions:

3 + 1048837 = 1048840
11 + 1048829 = 1048840
41 + 1048799 = 1048840
47 + 1048793 = 1048840
131 + 1048709 = 1048840
137 + 1048703 = 1048840
179 + 1048661 = 1048840
227 + 1048613 = 1048840

Showing the first eight; more decompositions exist.
