Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38724, here are decompositions:
- 11 + 38713 = 38724
- 13 + 38711 = 38724
- 17 + 38707 = 38724
- 31 + 38693 = 38724
- 47 + 38677 = 38724
- 53 + 38671 = 38724
- 71 + 38653 = 38724
- 73 + 38651 = 38724
Showing the first eight; more decompositions exist.
