Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494858, here are decompositions:

97 + 494761 = 494858
109 + 494749 = 494858
127 + 494731 = 494858
139 + 494719 = 494858
181 + 494677 = 494858
211 + 494647 = 494858
241 + 494617 = 494858
271 + 494587 = 494858

Showing the first eight; more decompositions exist.
