Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494888, here are decompositions:

127 + 494761 = 494888
139 + 494749 = 494888
151 + 494737 = 494888
157 + 494731 = 494888
211 + 494677 = 494888
241 + 494647 = 494888
271 + 494617 = 494888
349 + 494539 = 494888

Showing the first eight; more decompositions exist.
