Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87150, here are decompositions:

17 + 87133 = 87150
29 + 87121 = 87150
31 + 87119 = 87150
43 + 87107 = 87150
47 + 87103 = 87150
67 + 87083 = 87150
79 + 87071 = 87150
101 + 87049 = 87150

Showing the first eight; more decompositions exist.
