Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47240, here are decompositions:
- 3 + 47237 = 47240
- 19 + 47221 = 47240
- 79 + 47161 = 47240
- 97 + 47143 = 47240
- 103 + 47137 = 47240
- 181 + 47059 = 47240
- 199 + 47041 = 47240
- 223 + 47017 = 47240
Showing the first eight; more decompositions exist.
