Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42902, here are decompositions:
- 3 + 42899 = 42902
- 43 + 42859 = 42902
- 61 + 42841 = 42902
- 73 + 42829 = 42902
- 109 + 42793 = 42902
- 151 + 42751 = 42902
- 193 + 42709 = 42902
- 199 + 42703 = 42902
Showing the first eight; more decompositions exist.
