Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23828, here are decompositions:

61 + 23767 = 23828
67 + 23761 = 23828
109 + 23719 = 23828
139 + 23689 = 23828
151 + 23677 = 23828
157 + 23671 = 23828
199 + 23629 = 23828
229 + 23599 = 23828

Showing the first eight; more decompositions exist.
