Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47744, here are decompositions:
- 3 + 47741 = 47744
- 7 + 47737 = 47744
- 31 + 47713 = 47744
- 43 + 47701 = 47744
- 163 + 47581 = 47744
- 181 + 47563 = 47744
- 211 + 47533 = 47744
- 223 + 47521 = 47744
Showing the first eight; more decompositions exist.
