Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152668, here are decompositions:
- 11 + 152657 = 152668
- 29 + 152639 = 152668
- 71 + 152597 = 152668
- 101 + 152567 = 152668
- 137 + 152531 = 152668
- 149 + 152519 = 152668
- 167 + 152501 = 152668
- 227 + 152441 = 152668
Showing the first eight; more decompositions exist.
