Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558818, here are decompositions:

31 + 558787 = 558818
37 + 558781 = 558818
61 + 558757 = 558818
97 + 558721 = 558818
157 + 558661 = 558818
277 + 558541 = 558818
349 + 558469 = 558818
397 + 558421 = 558818

Showing the first eight; more decompositions exist.
