Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146816, here are decompositions:
- 67 + 146749 = 146816
- 73 + 146743 = 146816
- 97 + 146719 = 146816
- 139 + 146677 = 146816
- 199 + 146617 = 146816
- 277 + 146539 = 146816
- 367 + 146449 = 146816
- 379 + 146437 = 146816
Showing the first eight; more decompositions exist.
