Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021744, here are decompositions:

47 + 1021697 = 1021744
71 + 1021673 = 1021744
83 + 1021661 = 1021744
167 + 1021577 = 1021744
173 + 1021571 = 1021744
257 + 1021487 = 1021744
281 + 1021463 = 1021744
443 + 1021301 = 1021744

Showing the first eight; more decompositions exist.
