Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055628, here are decompositions:

17 + 1055611 = 1055628
19 + 1055609 = 1055628
31 + 1055597 = 1055628
37 + 1055591 = 1055628
61 + 1055567 = 1055628
97 + 1055531 = 1055628
127 + 1055501 = 1055628
139 + 1055489 = 1055628

Showing the first eight; more decompositions exist.
