Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052840, here are decompositions:

37 + 1052803 = 1052840
43 + 1052797 = 1052840
73 + 1052767 = 1052840
97 + 1052743 = 1052840
109 + 1052731 = 1052840
211 + 1052629 = 1052840
277 + 1052563 = 1052840
307 + 1052533 = 1052840

Showing the first eight; more decompositions exist.
