Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42504, here are decompositions:
- 5 + 42499 = 42504
- 13 + 42491 = 42504
- 17 + 42487 = 42504
- 31 + 42473 = 42504
- 37 + 42467 = 42504
- 41 + 42463 = 42504
- 43 + 42461 = 42504
- 47 + 42457 = 42504
Showing the first eight; more decompositions exist.
