Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494838, here are decompositions:

79 + 494759 = 494838
89 + 494749 = 494838
101 + 494737 = 494838
107 + 494731 = 494838
139 + 494699 = 494838
151 + 494687 = 494838
167 + 494671 = 494838
191 + 494647 = 494838

Showing the first eight; more decompositions exist.
