Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2472, here are decompositions:
- 5 + 2467 = 2472
- 13 + 2459 = 2472
- 31 + 2441 = 2472
- 61 + 2411 = 2472
- 73 + 2399 = 2472
- 79 + 2393 = 2472
- 83 + 2389 = 2472
- 89 + 2383 = 2472
Showing the first eight; more decompositions exist.
