Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508558, here are decompositions:

41 + 508517 = 508558
59 + 508499 = 508558
107 + 508451 = 508558
191 + 508367 = 508558
227 + 508331 = 508558
257 + 508301 = 508558
461 + 508097 = 508558
467 + 508091 = 508558

Showing the first eight; more decompositions exist.
