Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64378, here are decompositions:
- 5 + 64373 = 64378
- 59 + 64319 = 64378
- 107 + 64271 = 64378
- 191 + 64187 = 64378
- 227 + 64151 = 64378
- 269 + 64109 = 64378
- 311 + 64067 = 64378
- 359 + 64019 = 64378
Showing the first eight; more decompositions exist.
