Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669748, here are decompositions:

47 + 8669701 = 8669748
79 + 8669669 = 8669748
97 + 8669651 = 8669748
127 + 8669621 = 8669748
137 + 8669611 = 8669748
271 + 8669477 = 8669748
331 + 8669417 = 8669748
337 + 8669411 = 8669748

Showing the first eight; more decompositions exist.
