Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715980, here are decompositions:

3 + 8715977 = 8715980
19 + 8715961 = 8715980
43 + 8715937 = 8715980
73 + 8715907 = 8715980
79 + 8715901 = 8715980
103 + 8715877 = 8715980
139 + 8715841 = 8715980
193 + 8715787 = 8715980

Showing the first eight; more decompositions exist.
