Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981298, here are decompositions:

11 + 981287 = 981298
89 + 981209 = 981298
281 + 981017 = 981298
389 + 980909 = 981298
401 + 980897 = 981298
467 + 980831 = 981298
569 + 980729 = 981298
587 + 980711 = 981298

Showing the first eight; more decompositions exist.
