Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87908, here are decompositions:

31 + 87877 = 87908
97 + 87811 = 87908
157 + 87751 = 87908
211 + 87697 = 87908
229 + 87679 = 87908
277 + 87631 = 87908
349 + 87559 = 87908
367 + 87541 = 87908

Showing the first eight; more decompositions exist.
