Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51342, here are decompositions:
- 13 + 51329 = 51342
- 59 + 51283 = 51342
- 79 + 51263 = 51342
- 101 + 51241 = 51342
- 103 + 51239 = 51342
- 113 + 51229 = 51342
- 139 + 51203 = 51342
- 149 + 51193 = 51342
Showing the first eight; more decompositions exist.
