Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87144, here are decompositions:

11 + 87133 = 87144
23 + 87121 = 87144
37 + 87107 = 87144
41 + 87103 = 87144
61 + 87083 = 87144
73 + 87071 = 87144
103 + 87041 = 87144
107 + 87037 = 87144

Showing the first eight; more decompositions exist.
