Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8842, here are decompositions:

3 + 8839 = 8842
5 + 8837 = 8842
11 + 8831 = 8842
23 + 8819 = 8842
59 + 8783 = 8842
89 + 8753 = 8842
101 + 8741 = 8842
149 + 8693 = 8842

Showing the first eight; more decompositions exist.
