Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2758, here are decompositions:
- 5 + 2753 = 2758
- 17 + 2741 = 2758
- 29 + 2729 = 2758
- 47 + 2711 = 2758
- 59 + 2699 = 2758
- 71 + 2687 = 2758
- 101 + 2657 = 2758
- 137 + 2621 = 2758
Showing the first eight; more decompositions exist.
