Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040856, here are decompositions:

23 + 1040833 = 1040856
29 + 1040827 = 1040856
43 + 1040813 = 1040856
53 + 1040803 = 1040856
59 + 1040797 = 1040856
73 + 1040783 = 1040856
79 + 1040777 = 1040856
107 + 1040749 = 1040856

Showing the first eight; more decompositions exist.
