Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87928, here are decompositions:

11 + 87917 = 87928
17 + 87911 = 87928
41 + 87887 = 87928
47 + 87881 = 87928
59 + 87869 = 87928
131 + 87797 = 87928
227 + 87701 = 87928
257 + 87671 = 87928

Showing the first eight; more decompositions exist.
