Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2622, here are decompositions:
- 5 + 2617 = 2622
- 13 + 2609 = 2622
- 29 + 2593 = 2622
- 31 + 2591 = 2622
- 43 + 2579 = 2622
- 71 + 2551 = 2622
- 73 + 2549 = 2622
- 79 + 2543 = 2622
Showing the first eight; more decompositions exist.
