Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48018, here are decompositions:
- 37 + 47981 = 48018
- 41 + 47977 = 48018
- 67 + 47951 = 48018
- 71 + 47947 = 48018
- 79 + 47939 = 48018
- 101 + 47917 = 48018
- 107 + 47911 = 48018
- 137 + 47881 = 48018
Showing the first eight; more decompositions exist.
