Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146772, here are decompositions:
- 5 + 146767 = 146772
- 23 + 146749 = 146772
- 29 + 146743 = 146772
- 53 + 146719 = 146772
- 71 + 146701 = 146772
- 89 + 146683 = 146772
- 103 + 146669 = 146772
- 163 + 146609 = 146772
Showing the first eight; more decompositions exist.
