Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74138, here are decompositions:
- 7 + 74131 = 74138
- 37 + 74101 = 74138
- 61 + 74077 = 74138
- 67 + 74071 = 74138
- 139 + 73999 = 74138
- 199 + 73939 = 74138
- 241 + 73897 = 74138
- 271 + 73867 = 74138
Showing the first eight; more decompositions exist.
