Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83178, here are decompositions:
- 41 + 83137 = 83178
- 61 + 83117 = 83178
- 89 + 83089 = 83178
- 101 + 83077 = 83178
- 107 + 83071 = 83178
- 131 + 83047 = 83178
- 181 + 82997 = 83178
- 197 + 82981 = 83178
Showing the first eight; more decompositions exist.
