Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86876, here are decompositions:

7 + 86869 = 86876
19 + 86857 = 86876
109 + 86767 = 86876
157 + 86719 = 86876
199 + 86677 = 86876
277 + 86599 = 86876
337 + 86539 = 86876
367 + 86509 = 86876

Showing the first eight; more decompositions exist.
