Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64450, here are decompositions:
- 11 + 64439 = 64450
- 17 + 64433 = 64450
- 47 + 64403 = 64450
- 131 + 64319 = 64450
- 149 + 64301 = 64450
- 167 + 64283 = 64450
- 179 + 64271 = 64450
- 227 + 64223 = 64450
Showing the first eight; more decompositions exist.
