Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51312, here are decompositions:
- 5 + 51307 = 51312
- 29 + 51283 = 51312
- 71 + 51241 = 51312
- 73 + 51239 = 51312
- 83 + 51229 = 51312
- 109 + 51203 = 51312
- 113 + 51199 = 51312
- 179 + 51133 = 51312
Showing the first eight; more decompositions exist.
