Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557040, here are decompositions:

7 + 557033 = 557040
13 + 557027 = 557040
19 + 557021 = 557040
23 + 557017 = 557040
41 + 556999 = 557040
53 + 556987 = 557040
59 + 556981 = 557040
73 + 556967 = 557040

Showing the first eight; more decompositions exist.
