Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498578, here are decompositions:

109 + 498469 = 498578
139 + 498439 = 498578
181 + 498397 = 498578
211 + 498367 = 498578
277 + 498301 = 498578
307 + 498271 = 498578
397 + 498181 = 498578
601 + 497977 = 498578

Showing the first eight; more decompositions exist.
