Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64478, here are decompositions:
- 79 + 64399 = 64478
- 97 + 64381 = 64478
- 151 + 64327 = 64478
- 199 + 64279 = 64478
- 241 + 64237 = 64478
- 307 + 64171 = 64478
- 397 + 64081 = 64478
- 571 + 63907 = 64478
Showing the first eight; more decompositions exist.
