Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755820, here are decompositions:

79 + 8755741 = 8755820
97 + 8755723 = 8755820
109 + 8755711 = 8755820
181 + 8755639 = 8755820
421 + 8755399 = 8755820
439 + 8755381 = 8755820
499 + 8755321 = 8755820
523 + 8755297 = 8755820

Showing the first eight; more decompositions exist.
