Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558878, here are decompositions:

97 + 558781 = 558878
109 + 558769 = 558878
157 + 558721 = 558878
337 + 558541 = 558878
349 + 558529 = 558878
379 + 558499 = 558878
409 + 558469 = 558878
421 + 558457 = 558878

Showing the first eight; more decompositions exist.
