Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1053840, here are decompositions:

13 + 1053827 = 1053840
19 + 1053821 = 1053840
23 + 1053817 = 1053840
31 + 1053809 = 1053840
71 + 1053769 = 1053840
83 + 1053757 = 1053840
101 + 1053739 = 1053840
103 + 1053737 = 1053840

Showing the first eight; more decompositions exist.
