Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055640, here are decompositions:

29 + 1055611 = 1055640
31 + 1055609 = 1055640
37 + 1055603 = 1055640
43 + 1055597 = 1055640
73 + 1055567 = 1055640
97 + 1055543 = 1055640
109 + 1055531 = 1055640
137 + 1055503 = 1055640

Showing the first eight; more decompositions exist.
