Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669972, here are decompositions:

43 + 8669929 = 8669972
61 + 8669911 = 8669972
79 + 8669893 = 8669972
151 + 8669821 = 8669972
271 + 8669701 = 8669972
349 + 8669623 = 8669972
379 + 8669593 = 8669972
631 + 8669341 = 8669972

Showing the first eight; more decompositions exist.
