Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64744, here are decompositions:
- 83 + 64661 = 64744
- 131 + 64613 = 64744
- 167 + 64577 = 64744
- 191 + 64553 = 64744
- 293 + 64451 = 64744
- 311 + 64433 = 64744
- 443 + 64301 = 64744
- 461 + 64283 = 64744
Showing the first eight; more decompositions exist.
