Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51266, here are decompositions:
- 3 + 51263 = 51266
- 37 + 51229 = 51266
- 67 + 51199 = 51266
- 73 + 51193 = 51266
- 97 + 51169 = 51266
- 109 + 51157 = 51266
- 157 + 51109 = 51266
- 223 + 51043 = 51266
Showing the first eight; more decompositions exist.
