Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497858, here are decompositions:

7 + 497851 = 497858
19 + 497839 = 497858
139 + 497719 = 497858
157 + 497701 = 497858
181 + 497677 = 497858
199 + 497659 = 497858
271 + 497587 = 497858
307 + 497551 = 497858

Showing the first eight; more decompositions exist.
