Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2500, here are decompositions:
- 23 + 2477 = 2500
- 41 + 2459 = 2500
- 53 + 2447 = 2500
- 59 + 2441 = 2500
- 83 + 2417 = 2500
- 89 + 2411 = 2500
- 101 + 2399 = 2500
- 107 + 2393 = 2500
Showing the first eight; more decompositions exist.
