Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149968, here are decompositions:
- 29 + 149939 = 149968
- 47 + 149921 = 149968
- 59 + 149909 = 149968
- 101 + 149867 = 149968
- 107 + 149861 = 149968
- 131 + 149837 = 149968
- 197 + 149771 = 149968
- 239 + 149729 = 149968
Showing the first eight; more decompositions exist.
