Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044840, here are decompositions:

7 + 1044833 = 1044840
29 + 1044811 = 1044840
31 + 1044809 = 1044840
59 + 1044781 = 1044840
61 + 1044779 = 1044840
73 + 1044767 = 1044840
79 + 1044761 = 1044840
89 + 1044751 = 1044840

Showing the first eight; more decompositions exist.
