Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686804, here are decompositions:

83 + 8686721 = 8686804
101 + 8686703 = 8686804
317 + 8686487 = 8686804
383 + 8686421 = 8686804
431 + 8686373 = 8686804
443 + 8686361 = 8686804
491 + 8686313 = 8686804
563 + 8686241 = 8686804

Showing the first eight; more decompositions exist.
