Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000880, here are decompositions:

19 + 1000861 = 1000880
31 + 1000849 = 1000880
103 + 1000777 = 1000880
157 + 1000723 = 1000880
211 + 1000669 = 1000880
229 + 1000651 = 1000880
241 + 1000639 = 1000880
271 + 1000609 = 1000880

Showing the first eight; more decompositions exist.
