Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669990, here are decompositions:

61 + 8669929 = 8669990
67 + 8669923 = 8669990
79 + 8669911 = 8669990
97 + 8669893 = 8669990
223 + 8669767 = 8669990
367 + 8669623 = 8669990
379 + 8669611 = 8669990
397 + 8669593 = 8669990

Showing the first eight; more decompositions exist.
