Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021752, here are decompositions:

5 + 1021747 = 1021752
41 + 1021711 = 1021752
79 + 1021673 = 1021752
89 + 1021663 = 1021752
101 + 1021651 = 1021752
131 + 1021621 = 1021752
181 + 1021571 = 1021752
191 + 1021561 = 1021752

Showing the first eight; more decompositions exist.
