Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601800, here are decompositions:

61 + 8601739 = 8601800
73 + 8601727 = 8601800
379 + 8601421 = 8601800
409 + 8601391 = 8601800
439 + 8601361 = 8601800
457 + 8601343 = 8601800
523 + 8601277 = 8601800
547 + 8601253 = 8601800

Showing the first eight; more decompositions exist.
