Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028752, here are decompositions:

3 + 1028749 = 1028752
5 + 1028747 = 1028752
71 + 1028681 = 1028752
83 + 1028669 = 1028752
89 + 1028663 = 1028752
173 + 1028579 = 1028752
191 + 1028561 = 1028752
281 + 1028471 = 1028752

Showing the first eight; more decompositions exist.
