Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100876, here are decompositions:

23 + 100853 = 100876
29 + 100847 = 100876
47 + 100829 = 100876
53 + 100823 = 100876
89 + 100787 = 100876
107 + 100769 = 100876
173 + 100703 = 100876
227 + 100649 = 100876

Showing the first eight; more decompositions exist.
