Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87906, here are decompositions:

19 + 87887 = 87906
29 + 87877 = 87906
37 + 87869 = 87906
53 + 87853 = 87906
73 + 87833 = 87906
103 + 87803 = 87906
109 + 87797 = 87906
113 + 87793 = 87906

Showing the first eight; more decompositions exist.
