Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57902, here are decompositions:
- 3 + 57899 = 57902
- 43 + 57859 = 57902
- 73 + 57829 = 57902
- 109 + 57793 = 57902
- 151 + 57751 = 57902
- 193 + 57709 = 57902
- 223 + 57679 = 57902
- 331 + 57571 = 57902
Showing the first eight; more decompositions exist.
