Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007880, here are decompositions:

7 + 1007873 = 1007880
19 + 1007861 = 1007880
23 + 1007857 = 1007880
53 + 1007827 = 1007880
61 + 1007819 = 1007880
67 + 1007813 = 1007880
73 + 1007807 = 1007880
79 + 1007801 = 1007880

Showing the first eight; more decompositions exist.
