Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 459978, here are decompositions:

17 + 459961 = 459978
41 + 459937 = 459978
131 + 459847 = 459978
137 + 459841 = 459978
149 + 459829 = 459978
229 + 459749 = 459978
307 + 459671 = 459978
331 + 459647 = 459978

Showing the first eight; more decompositions exist.
