Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2488, here are decompositions:
- 11 + 2477 = 2488
- 29 + 2459 = 2488
- 41 + 2447 = 2488
- 47 + 2441 = 2488
- 71 + 2417 = 2488
- 89 + 2399 = 2488
- 107 + 2381 = 2488
- 131 + 2357 = 2488
Showing the first eight; more decompositions exist.
