Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558640, here are decompositions:

11 + 558629 = 558640
29 + 558611 = 558640
41 + 558599 = 558640
53 + 558587 = 558640
101 + 558539 = 558640
107 + 558533 = 558640
149 + 558491 = 558640
167 + 558473 = 558640

Showing the first eight; more decompositions exist.
