Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47408, here are decompositions:
- 19 + 47389 = 47408
- 139 + 47269 = 47408
- 157 + 47251 = 47408
- 271 + 47137 = 47408
- 349 + 47059 = 47408
- 367 + 47041 = 47408
- 541 + 46867 = 47408
- 547 + 46861 = 47408
Showing the first eight; more decompositions exist.
