Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702028, here are decompositions:

19 + 8702009 = 8702028
29 + 8701999 = 8702028
31 + 8701997 = 8702028
37 + 8701991 = 8702028
67 + 8701961 = 8702028
79 + 8701949 = 8702028
107 + 8701921 = 8702028
151 + 8701877 = 8702028

Showing the first eight; more decompositions exist.
