Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87148, here are decompositions:

29 + 87119 = 87148
41 + 87107 = 87148
107 + 87041 = 87148
137 + 87011 = 87148
167 + 86981 = 87148
179 + 86969 = 87148
197 + 86951 = 87148
311 + 86837 = 87148

Showing the first eight; more decompositions exist.
