Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719980, here are decompositions:

19 + 8719961 = 8719980
29 + 8719951 = 8719980
37 + 8719943 = 8719980
41 + 8719939 = 8719980
107 + 8719873 = 8719980
149 + 8719831 = 8719980
163 + 8719817 = 8719980
167 + 8719813 = 8719980

Showing the first eight; more decompositions exist.
