Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498278, here are decompositions:

7 + 498271 = 498278
19 + 498259 = 498278
97 + 498181 = 498278
349 + 497929 = 498278
379 + 497899 = 498278
409 + 497869 = 498278
439 + 497839 = 498278
541 + 497737 = 498278

Showing the first eight; more decompositions exist.
