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.
