Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8902, here are decompositions:

41 + 8861 = 8902
53 + 8849 = 8902
71 + 8831 = 8902
83 + 8819 = 8902
149 + 8753 = 8902
233 + 8669 = 8902
239 + 8663 = 8902
293 + 8609 = 8902

Showing the first eight; more decompositions exist.
