Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47312, here are decompositions:
- 3 + 47309 = 47312
- 19 + 47293 = 47312
- 43 + 47269 = 47312
- 61 + 47251 = 47312
- 151 + 47161 = 47312
- 163 + 47149 = 47312
- 193 + 47119 = 47312
- 271 + 47041 = 47312
Showing the first eight; more decompositions exist.
