Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021574, here are decompositions:

3 + 1021571 = 1021574
13 + 1021561 = 1021574
157 + 1021417 = 1021574
193 + 1021381 = 1021574
241 + 1021333 = 1021574
271 + 1021303 = 1021574
277 + 1021297 = 1021574
283 + 1021291 = 1021574

Showing the first eight; more decompositions exist.
