Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701980, here are decompositions:

19 + 8701961 = 8701980
29 + 8701951 = 8701980
31 + 8701949 = 8701980
47 + 8701933 = 8701980
59 + 8701921 = 8701980
73 + 8701907 = 8701980
97 + 8701883 = 8701980
103 + 8701877 = 8701980

Showing the first eight; more decompositions exist.
