Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2494, here are decompositions:
- 17 + 2477 = 2494
- 47 + 2447 = 2494
- 53 + 2441 = 2494
- 71 + 2423 = 2494
- 83 + 2411 = 2494
- 101 + 2393 = 2494
- 113 + 2381 = 2494
- 137 + 2357 = 2494
Showing the first eight; more decompositions exist.
