Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2616, here are decompositions:
- 7 + 2609 = 2616
- 23 + 2593 = 2616
- 37 + 2579 = 2616
- 59 + 2557 = 2616
- 67 + 2549 = 2616
- 73 + 2543 = 2616
- 113 + 2503 = 2616
- 139 + 2477 = 2616
Showing the first eight; more decompositions exist.
