Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47902, here are decompositions:
- 59 + 47843 = 47902
- 83 + 47819 = 47902
- 191 + 47711 = 47902
- 263 + 47639 = 47902
- 293 + 47609 = 47902
- 311 + 47591 = 47902
- 359 + 47543 = 47902
- 389 + 47513 = 47902
Showing the first eight; more decompositions exist.
