Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47644, here are decompositions:
- 5 + 47639 = 47644
- 53 + 47591 = 47644
- 101 + 47543 = 47644
- 131 + 47513 = 47644
- 137 + 47507 = 47644
- 227 + 47417 = 47644
- 257 + 47387 = 47644
- 263 + 47381 = 47644
Showing the first eight; more decompositions exist.
