Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77902, here are decompositions:
- 3 + 77899 = 77902
- 53 + 77849 = 77902
- 89 + 77813 = 77902
- 101 + 77801 = 77902
- 179 + 77723 = 77902
- 191 + 77711 = 77902
- 281 + 77621 = 77902
- 311 + 77591 = 77902
Showing the first eight; more decompositions exist.
