Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7848, here are decompositions:
- 7 + 7841 = 7848
- 19 + 7829 = 7848
- 31 + 7817 = 7848
- 59 + 7789 = 7848
- 89 + 7759 = 7848
- 107 + 7741 = 7848
- 131 + 7717 = 7848
- 149 + 7699 = 7848
Showing the first eight; more decompositions exist.
