Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51372, here are decompositions:
- 11 + 51361 = 51372
- 23 + 51349 = 51372
- 29 + 51343 = 51372
- 31 + 51341 = 51372
- 43 + 51329 = 51372
- 89 + 51283 = 51372
- 109 + 51263 = 51372
- 131 + 51241 = 51372
Showing the first eight; more decompositions exist.
