Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558278, here are decompositions:

37 + 558241 = 558278
139 + 558139 = 558278
157 + 558121 = 558278
211 + 558067 = 558278
271 + 558007 = 558278
379 + 557899 = 558278
421 + 557857 = 558278
499 + 557779 = 558278

Showing the first eight; more decompositions exist.
