Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2792, here are decompositions:
- 3 + 2789 = 2792
- 43 + 2749 = 2792
- 61 + 2731 = 2792
- 73 + 2719 = 2792
- 79 + 2713 = 2792
- 103 + 2689 = 2792
- 109 + 2683 = 2792
- 199 + 2593 = 2792
Showing the first eight; more decompositions exist.
