Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15398, here are decompositions:
- 7 + 15391 = 15398
- 37 + 15361 = 15398
- 67 + 15331 = 15398
- 79 + 15319 = 15398
- 109 + 15289 = 15398
- 127 + 15271 = 15398
- 139 + 15259 = 15398
- 157 + 15241 = 15398
Showing the first eight; more decompositions exist.
