Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497978, here are decompositions:

79 + 497899 = 497978
109 + 497869 = 497978
127 + 497851 = 497978
139 + 497839 = 497978
241 + 497737 = 497978
277 + 497701 = 497978
307 + 497671 = 497978
421 + 497557 = 497978

Showing the first eight; more decompositions exist.
