Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029880, here are decompositions:

41 + 1029839 = 1029880
53 + 1029827 = 1029880
113 + 1029767 = 1029880
149 + 1029731 = 1029880
191 + 1029689 = 1029880
227 + 1029653 = 1029880
233 + 1029647 = 1029880
263 + 1029617 = 1029880

Showing the first eight; more decompositions exist.
