Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558660, here are decompositions:

17 + 558643 = 558660
31 + 558629 = 558660
61 + 558599 = 558660
73 + 558587 = 558660
97 + 558563 = 558660
127 + 558533 = 558660
131 + 558529 = 558660
139 + 558521 = 558660

Showing the first eight; more decompositions exist.
