Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701100, here are decompositions:

19 + 8701081 = 8701100
43 + 8701057 = 8701100
61 + 8701039 = 8701100
73 + 8701027 = 8701100
229 + 8700871 = 8701100
283 + 8700817 = 8701100
307 + 8700793 = 8701100
349 + 8700751 = 8701100

Showing the first eight; more decompositions exist.
