Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978298, here are decompositions:

11 + 978287 = 978298
29 + 978269 = 978298
59 + 978239 = 978298
89 + 978209 = 978298
149 + 978149 = 978298
227 + 978071 = 978298
257 + 978041 = 978298
281 + 978017 = 978298

Showing the first eight; more decompositions exist.
