Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690900, here are decompositions:

73 + 8690827 = 8690900
79 + 8690821 = 8690900
103 + 8690797 = 8690900
223 + 8690677 = 8690900
241 + 8690659 = 8690900
307 + 8690593 = 8690900
349 + 8690551 = 8690900
487 + 8690413 = 8690900

Showing the first eight; more decompositions exist.
