Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51404, here are decompositions:
- 43 + 51361 = 51404
- 61 + 51343 = 51404
- 97 + 51307 = 51404
- 163 + 51241 = 51404
- 211 + 51193 = 51404
- 271 + 51133 = 51404
- 373 + 51031 = 51404
- 433 + 50971 = 51404
Showing the first eight; more decompositions exist.
