Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669902, here are decompositions:

5 + 8669897 = 8669902
23 + 8669879 = 8669902
41 + 8669861 = 8669902
71 + 8669831 = 8669902
233 + 8669669 = 8669902
251 + 8669651 = 8669902
281 + 8669621 = 8669902
359 + 8669543 = 8669902

Showing the first eight; more decompositions exist.
