Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39924, here are decompositions:
- 23 + 39901 = 39924
- 37 + 39887 = 39924
- 41 + 39883 = 39924
- 47 + 39877 = 39924
- 61 + 39863 = 39924
- 67 + 39857 = 39924
- 83 + 39841 = 39924
- 97 + 39827 = 39924
Showing the first eight; more decompositions exist.
