Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498740, here are decompositions:

7 + 498733 = 498740
61 + 498679 = 498740
97 + 498643 = 498740
127 + 498613 = 498740
157 + 498583 = 498740
163 + 498577 = 498740
271 + 498469 = 498740
331 + 498409 = 498740

Showing the first eight; more decompositions exist.
