Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87126, here are decompositions:

5 + 87121 = 87126
7 + 87119 = 87126
19 + 87107 = 87126
23 + 87103 = 87126
43 + 87083 = 87126
89 + 87037 = 87126
113 + 87013 = 87126
157 + 86969 = 87126

Showing the first eight; more decompositions exist.
