Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2470, here are decompositions:
- 3 + 2467 = 2470
- 11 + 2459 = 2470
- 23 + 2447 = 2470
- 29 + 2441 = 2470
- 47 + 2423 = 2470
- 53 + 2417 = 2470
- 59 + 2411 = 2470
- 71 + 2399 = 2470
Showing the first eight; more decompositions exist.
