Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2662, here are decompositions:
- 3 + 2659 = 2662
- 5 + 2657 = 2662
- 29 + 2633 = 2662
- 41 + 2621 = 2662
- 53 + 2609 = 2662
- 71 + 2591 = 2662
- 83 + 2579 = 2662
- 113 + 2549 = 2662
Showing the first eight; more decompositions exist.
