Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029840, here are decompositions:

13 + 1029827 = 1029840
17 + 1029823 = 1029840
37 + 1029803 = 1029840
73 + 1029767 = 1029840
83 + 1029757 = 1029840
89 + 1029751 = 1029840
109 + 1029731 = 1029840
151 + 1029689 = 1029840

Showing the first eight; more decompositions exist.
