Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47378, here are decompositions:
- 61 + 47317 = 47378
- 109 + 47269 = 47378
- 127 + 47251 = 47378
- 157 + 47221 = 47378
- 229 + 47149 = 47378
- 241 + 47137 = 47378
- 337 + 47041 = 47378
- 421 + 46957 = 47378
Showing the first eight; more decompositions exist.
