Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23100, here are decompositions:

13 + 23087 = 23100
19 + 23081 = 23100
29 + 23071 = 23100
37 + 23063 = 23100
41 + 23059 = 23100
43 + 23057 = 23100
47 + 23053 = 23100
59 + 23041 = 23100

Showing the first eight; more decompositions exist.
