Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7838, here are decompositions:
- 79 + 7759 = 7838
- 97 + 7741 = 7838
- 139 + 7699 = 7838
- 151 + 7687 = 7838
- 157 + 7681 = 7838
- 199 + 7639 = 7838
- 277 + 7561 = 7838
- 331 + 7507 = 7838
Showing the first eight; more decompositions exist.
