Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15342, here are decompositions:
- 11 + 15331 = 15342
- 13 + 15329 = 15342
- 23 + 15319 = 15342
- 29 + 15313 = 15342
- 43 + 15299 = 15342
- 53 + 15289 = 15342
- 71 + 15271 = 15342
- 73 + 15269 = 15342
Showing the first eight; more decompositions exist.
