Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746880, here are decompositions:

7 + 8746873 = 8746880
19 + 8746861 = 8746880
31 + 8746849 = 8746880
61 + 8746819 = 8746880
67 + 8746813 = 8746880
73 + 8746807 = 8746880
127 + 8746753 = 8746880
157 + 8746723 = 8746880

Showing the first eight; more decompositions exist.
