Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47972, here are decompositions:
- 3 + 47969 = 47972
- 61 + 47911 = 47972
- 103 + 47869 = 47972
- 163 + 47809 = 47972
- 181 + 47791 = 47972
- 193 + 47779 = 47972
- 229 + 47743 = 47972
- 271 + 47701 = 47972
Showing the first eight; more decompositions exist.
