Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719004, here are decompositions:

31 + 8718973 = 8719004
97 + 8718907 = 8719004
127 + 8718877 = 8719004
181 + 8718823 = 8719004
193 + 8718811 = 8719004
211 + 8718793 = 8719004
271 + 8718733 = 8719004
277 + 8718727 = 8719004

Showing the first eight; more decompositions exist.
