Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23120, here are decompositions:
- 3 + 23117 = 23120
- 61 + 23059 = 23120
- 67 + 23053 = 23120
- 79 + 23041 = 23120
- 103 + 23017 = 23120
- 109 + 23011 = 23120
- 127 + 22993 = 23120
- 157 + 22963 = 23120
Showing the first eight; more decompositions exist.
