Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719100, here are decompositions:

43 + 8719057 = 8719100
79 + 8719021 = 8719100
97 + 8719003 = 8719100
127 + 8718973 = 8719100
151 + 8718949 = 8719100
193 + 8718907 = 8719100
223 + 8718877 = 8719100
241 + 8718859 = 8719100

Showing the first eight; more decompositions exist.
