Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72048, here are decompositions:
- 5 + 72043 = 72048
- 17 + 72031 = 72048
- 29 + 72019 = 72048
- 61 + 71987 = 72048
- 101 + 71947 = 72048
- 107 + 71941 = 72048
- 131 + 71917 = 72048
- 139 + 71909 = 72048
Showing the first eight; more decompositions exist.
