Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055550, here are decompositions:

7 + 1055543 = 1055550
19 + 1055531 = 1055550
47 + 1055503 = 1055550
61 + 1055489 = 1055550
79 + 1055471 = 1055550
113 + 1055437 = 1055550
127 + 1055423 = 1055550
137 + 1055413 = 1055550

Showing the first eight; more decompositions exist.
