Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684870, here are decompositions:

109 + 8684761 = 8684870
157 + 8684713 = 8684870
241 + 8684629 = 8684870
283 + 8684587 = 8684870
349 + 8684521 = 8684870
367 + 8684503 = 8684870
409 + 8684461 = 8684870
433 + 8684437 = 8684870

Showing the first eight; more decompositions exist.
