Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63904, here are decompositions:
- 3 + 63901 = 63904
- 41 + 63863 = 63904
- 47 + 63857 = 63904
- 101 + 63803 = 63904
- 131 + 63773 = 63904
- 167 + 63737 = 63904
- 233 + 63671 = 63904
- 257 + 63647 = 63904
Showing the first eight; more decompositions exist.
