Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555450, here are decompositions:

11 + 555439 = 555450
29 + 555421 = 555450
31 + 555419 = 555450
59 + 555391 = 555450
67 + 555383 = 555450
89 + 555361 = 555450
101 + 555349 = 555450
113 + 555337 = 555450

Showing the first eight; more decompositions exist.
