Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87112, here are decompositions:

5 + 87107 = 87112
29 + 87083 = 87112
41 + 87071 = 87112
71 + 87041 = 87112
101 + 87011 = 87112
131 + 86981 = 87112
173 + 86939 = 87112
251 + 86861 = 87112

Showing the first eight; more decompositions exist.
