Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23138, here are decompositions:
- 7 + 23131 = 23138
- 67 + 23071 = 23138
- 79 + 23059 = 23138
- 97 + 23041 = 23138
- 109 + 23029 = 23138
- 127 + 23011 = 23138
- 277 + 22861 = 23138
- 331 + 22807 = 23138
Showing the first eight; more decompositions exist.
