Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87958, here are decompositions:

41 + 87917 = 87958
47 + 87911 = 87958
71 + 87887 = 87958
89 + 87869 = 87958
191 + 87767 = 87958
239 + 87719 = 87958
257 + 87701 = 87958
317 + 87641 = 87958

Showing the first eight; more decompositions exist.
