Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8920, here are decompositions:

53 + 8867 = 8920
59 + 8861 = 8920
71 + 8849 = 8920
83 + 8837 = 8920
89 + 8831 = 8920
101 + 8819 = 8920
113 + 8807 = 8920
137 + 8783 = 8920

Showing the first eight; more decompositions exist.
