Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47172, here are decompositions:
- 11 + 47161 = 47172
- 23 + 47149 = 47172
- 29 + 47143 = 47172
- 43 + 47129 = 47172
- 53 + 47119 = 47172
- 61 + 47111 = 47172
- 79 + 47093 = 47172
- 113 + 47059 = 47172
Showing the first eight; more decompositions exist.
