Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021498, here are decompositions:

11 + 1021487 = 1021498
41 + 1021457 = 1021498
131 + 1021367 = 1021498
167 + 1021331 = 1021498
197 + 1021301 = 1021498
227 + 1021271 = 1021498
239 + 1021259 = 1021498
281 + 1021217 = 1021498

Showing the first eight; more decompositions exist.
