Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7846, here are decompositions:
- 5 + 7841 = 7846
- 17 + 7829 = 7846
- 23 + 7823 = 7846
- 29 + 7817 = 7846
- 53 + 7793 = 7846
- 89 + 7757 = 7846
- 173 + 7673 = 7846
- 197 + 7649 = 7846
Showing the first eight; more decompositions exist.
