Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494990, here are decompositions:

3 + 494987 = 494990
31 + 494959 = 494990
73 + 494917 = 494990
229 + 494761 = 494990
241 + 494749 = 494990
271 + 494719 = 494990
277 + 494713 = 494990
313 + 494677 = 494990

Showing the first eight; more decompositions exist.
