Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558778, here are decompositions:

47 + 558731 = 558778
149 + 558629 = 558778
167 + 558611 = 558778
179 + 558599 = 558778
191 + 558587 = 558778
239 + 558539 = 558778
257 + 558521 = 558778
281 + 558497 = 558778

Showing the first eight; more decompositions exist.
