Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2732, here are decompositions:
- 3 + 2729 = 2732
- 13 + 2719 = 2732
- 19 + 2713 = 2732
- 43 + 2689 = 2732
- 61 + 2671 = 2732
- 73 + 2659 = 2732
- 139 + 2593 = 2732
- 181 + 2551 = 2732
Showing the first eight; more decompositions exist.
