Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756210, here are decompositions:

7 + 8756203 = 8756210
61 + 8756149 = 8756210
97 + 8756113 = 8756210
103 + 8756107 = 8756210
109 + 8756101 = 8756210
487 + 8755723 = 8756210
499 + 8755711 = 8756210
571 + 8755639 = 8756210

Showing the first eight; more decompositions exist.
