Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2754, here are decompositions:
- 5 + 2749 = 2754
- 13 + 2741 = 2754
- 23 + 2731 = 2754
- 41 + 2713 = 2754
- 43 + 2711 = 2754
- 47 + 2707 = 2754
- 61 + 2693 = 2754
- 67 + 2687 = 2754
Showing the first eight; more decompositions exist.
