Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155968, here are decompositions:
- 47 + 155921 = 155968
- 107 + 155861 = 155968
- 167 + 155801 = 155968
- 191 + 155777 = 155968
- 227 + 155741 = 155968
- 251 + 155717 = 155968
- 269 + 155699 = 155968
- 311 + 155657 = 155968
Showing the first eight; more decompositions exist.
