Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64256, here are decompositions:
- 19 + 64237 = 64256
- 67 + 64189 = 64256
- 103 + 64153 = 64256
- 193 + 64063 = 64256
- 223 + 64033 = 64256
- 307 + 63949 = 64256
- 349 + 63907 = 64256
- 433 + 63823 = 64256
Showing the first eight; more decompositions exist.
