Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163902, here are decompositions:
- 19 + 163883 = 163902
- 31 + 163871 = 163902
- 41 + 163861 = 163902
- 43 + 163859 = 163902
- 61 + 163841 = 163902
- 83 + 163819 = 163902
- 113 + 163789 = 163902
- 131 + 163771 = 163902
Showing the first eight; more decompositions exist.
