Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498438, here are decompositions:

29 + 498409 = 498438
37 + 498401 = 498438
41 + 498397 = 498438
47 + 498391 = 498438
71 + 498367 = 498438
107 + 498331 = 498438
137 + 498301 = 498438
167 + 498271 = 498438

Showing the first eight; more decompositions exist.
