Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143680, here are decompositions:
- 3 + 143677 = 143680
- 11 + 143669 = 143680
- 29 + 143651 = 143680
- 71 + 143609 = 143680
- 107 + 143573 = 143680
- 113 + 143567 = 143680
- 167 + 143513 = 143680
- 179 + 143501 = 143680
Showing the first eight; more decompositions exist.
