Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64388, here are decompositions:
- 7 + 64381 = 64388
- 61 + 64327 = 64388
- 109 + 64279 = 64388
- 151 + 64237 = 64388
- 157 + 64231 = 64388
- 199 + 64189 = 64388
- 307 + 64081 = 64388
- 439 + 63949 = 64388
Showing the first eight; more decompositions exist.
