Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74120, here are decompositions:
- 19 + 74101 = 74120
- 43 + 74077 = 74120
- 73 + 74047 = 74120
- 103 + 74017 = 74120
- 181 + 73939 = 74120
- 223 + 73897 = 74120
- 271 + 73849 = 74120
- 337 + 73783 = 74120
Showing the first eight; more decompositions exist.
