Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684900, here are decompositions:

79 + 8684821 = 8684900
139 + 8684761 = 8684900
271 + 8684629 = 8684900
313 + 8684587 = 8684900
379 + 8684521 = 8684900
397 + 8684503 = 8684900
421 + 8684479 = 8684900
439 + 8684461 = 8684900

Showing the first eight; more decompositions exist.
