Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47342, here are decompositions:
- 3 + 47339 = 47342
- 73 + 47269 = 47342
- 181 + 47161 = 47342
- 193 + 47149 = 47342
- 199 + 47143 = 47342
- 223 + 47119 = 47342
- 283 + 47059 = 47342
- 349 + 46993 = 47342
Showing the first eight; more decompositions exist.
