Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497990, here are decompositions:

13 + 497977 = 497990
61 + 497929 = 497990
139 + 497851 = 497990
151 + 497839 = 497990
271 + 497719 = 497990
313 + 497677 = 497990
331 + 497659 = 497990
433 + 497557 = 497990

Showing the first eight; more decompositions exist.
