Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64400, here are decompositions:
- 19 + 64381 = 64400
- 67 + 64333 = 64400
- 73 + 64327 = 64400
- 97 + 64303 = 64400
- 163 + 64237 = 64400
- 211 + 64189 = 64400
- 229 + 64171 = 64400
- 277 + 64123 = 64400
Showing the first eight; more decompositions exist.
