Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23130, here are decompositions:

13 + 23117 = 23130
31 + 23099 = 23130
43 + 23087 = 23130
59 + 23071 = 23130
67 + 23063 = 23130
71 + 23059 = 23130
73 + 23057 = 23130
89 + 23041 = 23130

Showing the first eight; more decompositions exist.
